Internet Marketer Wanted to Grow Paid Subscriptions for Invoicing App

I’m looking for a results-driven internet marketer to acquire real paying subscribers for CostInvoice, a simple, fast, and affordable invoicing platform built for freelancers, solo entrepreneurs, and small business owners.
CostInvoice helps users create clean invoices instantly, accept payments online (Stripe/PayPal), and keep their billing workflow friction-free — without the complexity of accounting software.

🎯 Goal:

Acquire $10/month paying subscribers — not just free trials.

• Run highly targeted, ROI-focused paid ad campaigns designed to attract high-intent users who convert into paying subscribers — not generic traffic.
• Own the full acquisition funnel, continuously optimizing ads, landing pages, messaging, and targeting based on conversion data.
• Deliver weekly performance reports detailing:
• Subscriber growth (trials → paid)
• Revenue generated
• Profitability of each campaign
• CAC, ROAS, and recommendations for scaling
