[Hiring] Telegram Bot + Simple Website Developer for Username Store ($100 Budget)

Hello, I’m looking for a developer to build a simple but smart system for selling premium social media usernames. This is not a public marketplace, since all usernames are owned and managed by me. I want the main control to be through a Telegram bot with an easy admin interface where I can add the username, email, password, platform, and transfer instructions, and once I add it there, it should automatically appear on the website without needing to upload it again manually.
Users should be able to buy either from the website or directly from the Telegram bot, and if someone starts buying a certain username, it must instantly be put on hold across both platforms to prevent double purchases. I also want the system to automatically generate a clean visual design for each listing, including the username, platform icon, follower count, and account age, with follower count and account age fetched automatically instead of being entered manually.
The system should support payments via crypto (USDT/Binance Pay) and Telegram Stars. If a user chooses to pay with Telegram Stars from the website, they should be redirected to the bot to complete the payment. After a Telegram Stars payment is completed, the username should be marked as sold and locked, but delivery must be delayed for 22 days before the buyer receives the account details or transfer instructions, to prevent refunds.
In addition, I want to include a paid extra feature for Instagram username swap guidance between two accounts, where the user pays $1 each time to access that feature through the bot. The system should be clean, simple, reliable, and easy for me to manage, and my budget is around $100, so I’m mainly looking for a basic working MVP rather than something overly complex. I’m looking for someone experienced with Telegram bots, websites, payment integration, automation, and ideally Instagram-related workflows.
