Telegram Funnel & Meta Ads Expert

Job Description:I need an experienced Telegram bot developer to build a fully automated onboarding and upgrade funnel for my trading community ("The Syndicate"). The bot must handle the entire user journey from their first click on the free channel link to automatically upgrading them to our paid VIP group.Here is the exact flow the bot must execute:Auto-Approve & DM (The Gatekeeper): The bot must act as an admin on my free channel. When a user clicks a "Request Admin Approval" invite link, the bot must instantly approve them and simultaneously send them a private Welcome Message via DM. The VIP Pitch: The welcome DM must explain the benefits of our VIP group and immediately present our $29 Lifetime access offer alongside the payment details/link. Payment Verification & Access: Once the user completes the payment, the bot needs to verify the transaction and automatically provide them with a single-use invite link (or directly add them) to the private VIP channel. Key Deliverables:Telegram API integration specifically utilizing "Chat Join Requests" to enable the auto-DM upon joining. Automated delivery of the VIP pitch and payment instructions. Integration for payment verification (USDT/Crypto wallet checking or a standard gateway like Stripe).Automated management of private channel access (generating one-time invite links for paid users and revoking access if necessary).I am looking for a developer who has built this exact "auto-approval to paid VIP" bot structure before. Please apply with examples, screenshots, or live bot usernames of similar subscription bots you have coded.
