Need asap

"I own a marketing agency and I need a fully automated, white-labeled lead generation system built that I can resell to my clients as a service. My clients pay me monthly and I deliver them verified, targeted leads — I need the system to handle up to 50,000-200,000 leads per month across multiple clients simultaneously. The system must automatically pull leads based on each client's target industry, location, and ideal customer profile and deliver verified leads including business name, decision-maker name (Founders, CEOs, Heads of Sales, VPs of Marketing), phone number, email, website, and address. It must be white-labeled so it looks like my agency's product, handle multiple client campaigns at once with separate dashboards per client, export or deliver leads automatically via CSV, Google Sheets, CRM, or direct email, and require zero manual work from me once a client is onboarded. Bonus features I want include an AI voice agent that calls leads on my clients' behalf, automated email and SMS follow-up sequences, a white-label client portal where each client logs in and sees their own leads, GoHighLevel integration, and billing/subscription management for my clients. I want to own this system — not rent a SaaS tool. Budget is open based on scope and I need this built ASAP as I have clients ready to onboard." one time payment.
