GoHighLevel Expert Needed to Build Missed-Call Lead Recovery System for HVAC/Plumbing Agency

I'm starting a digital agency focused on helping local plumbing and HVAC companies in Ontario, Canada recover leads from missed calls. I need an experienced GoHighLevel expert to build the first version of our system. What I want to build The core workflow is: Customer calls a plumbing/HVAC company → business misses the call → automated follow-up is sent → customer can respond → lead is captured in GoHighLevel → business is notified → lead can be followed up/booked. The system will be offered to local businesses through a 14-day free trial. The system should include Missed-call trigger Automated missed-call follow-up Two-way SMS Contact/lead creation CRM pipeline Lead notifications Appointment/booking functionality Basic lead tracking/reporting 14-day trial workflow Opt-out handling Reusable GHL snapshot/template Easy client onboarding Testing of the complete workflow Important I want this built as a reusable system for my agency. Once we onboard another plumbing or HVAC company, I should be able to duplicate the setup and customize things such as: Business name Phone number Services Service area Business hours Staff notifications Booking link Message wording I don't want a complicated system filled with unnecessary features. The priority is: Missed call → immediate follow-up → customer response → lead captured → business notified → appointment opportunity. What I'm looking for I'm looking for someone who has real GoHighLevel experience, not someone learning the platform for the first time. Experience with: GoHighLevel CRM workflows Missed-call text-back SMS automation Lead capture Appointment booking Snapshots/reusable templates Local service businesses is highly preferred. Before starting Please explain in your proposal: How you would build this system. Whether you've built a missed-call recovery system before. How you would make it reusable for multiple clients. What integrations/third-party tools you'd need. How long you expect the build to take. What ongoing software costs I should expect. Examples/screenshots/videos of similar GHL systems you've personally built. Please do not start building before we agree on the scope and milestones. Deliverables At the end of the project I want: Fully working GHL workflow Reusable snapshot/template Tested missed-call workflow CRM pipeline Notifications Trial workflow Basic reporting Setup instructions Short walkthrough video showing me how everything works Instructions for duplicating the system for a new client Budget $750 USD fixed price I'm open to discussing milestones based on the exact scope. If the project goes well, there is potential for ongoing/full-time work as we onboard more HVAC and plumbing clients. Application Start your proposal with: GHL BUILDER Then tell me briefly: 1. How many GHL projects have you built? 2. Have you built missed-call follow-up before? 3. Have you built GHL snapshots? 4. Show me an example of relevant work. 5. How would you build the workflow described above?
