Most GoHighLevel accounts don't fail because of the platform. They fail because the funnel, CRM, and automations were never planned out properly in the first place. I help small businesses, agencies, coaches, consultants, and service businesses build or fix GoHighLevel systems that are clean, focused on getting results, and reliable in everyday use and not just in theory. If your funnels aren't converting, your workflows are firing at the wrong time, your pipeline is a mess, or your team isn't using the system the way it should be used, I can help turn GoHighLevel into a system that actually brings in revenue. I specialize in: ✅ GoHighLevel funnel setup and landing pages ✅ CRM and pipeline setup ✅ Workflow automation and lead nurture systems ✅ Booking and appointment automation ✅ Missed-call text-back and follow-up sequences ✅ Snapshot creation and sub-account setup ✅ Integrations with Twilio, Zapier, Make, Stripe, calendars, and webhooks ✅ GoHighLevel audits, cleanup, and rebuilds My approach is simple: I plan everything out before I build. That means I start by understanding how your leads should flow from first contact to booked call, through your pipeline, follow-up, and reporting. From there, I build systems that are easy to manage, clearly labeled, tested from start to finish, and built to last. What you can hire me for: ✅ GoHighLevel Funnels: lead generation funnels, booking funnels, webinar funnels, VSL funnels, quiz funnels, application funnels, landing page optimization, and mobile-friendly funnel builds ✅ Automation & Workflows: SMS and email follow-up, nurture sequences, reactivation campaigns, missed-call text-back, stage-based automation, after-hours workflows, and lead routing ✅ CRM & Pipeline Setup: pipeline design, opportunity stages, tags, segmentation, lead routing, and organized account setup ✅ Agency & Scaling Systems: sub-account builds, snapshots, ready-to-clone templates, SaaS mode support, onboarding workflows, and clean handoff ✅ Integrations & Operations: Twilio setup, Stripe, Zapier, Make, webhooks, calendars, tracking where leads come from, data cleanup, and reporting support What clients appreciate most about working with me: ✅ Clean, organized systems ✅ Automations that work reliably ✅ Funnels built with conversion in mind ✅ Clear communication ✅ Everything properly tested before handoff ✅ Loom walkthroughs and simple written notes for easy use after delivery Whether you need a full build from scratch, an audit of a messy account, or a smarter automation system inside GoHighLevel, I can help you get it working the right way. Send me a message with what you're selling, what's not working, and where you're getting stuck. I'll help you map out the best next step.

If your Kajabi course looks unfinished or your sales page isn't turning visitors into students, the problem usually isn't your content. It's the system around it. I build the full course setup for coaches: the Kajabi Website, the course structure, the sales page, and the funnel that connects them. You've got the expertise. I make sure the platform doesn't get in the way of it. Who I work with I help coaches, consultants, and course creators who have knowledge worth teaching but no clear system to sell or deliver it. That includes life coaches, business coaches, health and wellness experts, and consultants moving their programs online for the first time. It also includes people who already have a course live on Kajabi, Thinkific, or LearnWorlds but know the platform isn't pulling its weight. This work shows up across a lot of industries: business and leadership coaching, health and fitness, beauty and creative education, consulting and finance, and corporate training or certification programs. The platform changes shape depending on the audience, but the goal stays the same. Students need a clear path from sign-up to finished course, and you need a system that sells without you manually chasing every lead. Problems I fix 🟢 A Kajabi Website that looks unfinished, generic, or hard for visitors to navigate 🟢 A Kajabi Sales Page that doesn't clearly explain the offer or give people a reason to buy 🟢 Modules and lessons that feel disorganized, making students drop off before they finish 🟢 No real funnel. Leads come in but nothing moves them toward enrollment 🟢 Manual busywork like uploading lessons, building offers, and managing contacts that eats up your week 🟢 A Thinkific or LearnWorlds platform that needs better structure or a proper redesign 🟢 Broken links, messy navigation, or a checkout process that loses buyers at the last step 🟢 No clear path from opt-in to purchase, so warm leads go cold before they enroll 🟢 A course that took months to build but still doesn't look like it's worth the price you're charging What I do 🟢 Design and build a complete Kajabi Website, from homepage to course portal to checkout 🟢 Write and design a Kajabi Sales Page that lays out your offer, pricing, and proof clearly 🟢 Organize your curriculum into modules, lessons, quizzes, and downloads that make sense to a student 🟢 Set up the full funnel: opt-in page, email sequence, checkout, and onboarding, all connected 🟢 Handle the ongoing Kajabi admin work: uploads, offers, coupons, contacts, and testing 🟢 Set up or rebuild courses on Thinkific and LearnWorlds when Kajabi isn't the right fit 🟢 Connect payment processing, automations, and email tools so the whole system runs on its own 🟢 Test every link, form, and step in the student journey before you ever launch How I work I start by looking at what you already have, whether that's a half-built Kajabi account or a course that's been live for a year but stalled. From there I map out what's missing: design, structure, or the sales and email system that moves people from interested to enrolled. Then I build it piece by piece, so nothing you launch is disconnected or untested. I've spent years inside Kajabi, Thinkific, and LearnWorlds, so I know where each platform is strong and where it needs a workaround. That means less time explaining what you want and more time getting it built right the first time. I also work comfortably alongside tools like ConvertKit, ActiveCampaign, Stripe, PayPal, and Zapier, so your course platform connects cleanly to whatever else you're already running. A general web designer can make a page look nice. What they miss is how Kajabi works: how offers connect to checkout, how pipelines move a lead through email, how a broken automation quietly kills enrollments without anyone noticing. That's what I focus on, because a course platform only earns its keep when the pages, payments, and follow-up work as one system. Whether you're launching your first course or fixing one that isn't converting, the goal is the same: a Kajabi Website, Kajabi Sales Page, and funnel that work together instead of fighting each other. I keep communication straightforward. You'll know what stage the build is at, what I need from you, and what's coming next, so there are no surprises between kickoff and launch day. I treat your course the way I'd treat my own, which means I'm not handing back a project until every page loads right and every link works. If your course platform feels like it's holding you back instead of helping you sell, send me a message. Tell me what's not working, whether it's the design, the sales page, or the setup, and I'll tell you exactly how I'd fix it and what it would take to get it live.
