I need a reliable developer for an ongoing monthly task (1-2 years commitment): Every month I will send you a list of 4000-5000 usernames (CSV or TXT file). Your only job is to add these users to my public Telegram supergroup. Requirements: - You create a fast and safe bulk member adder (Telethon or Pyrogram – MTProto/userbot method). - You run the adding process every month when I send the new list. - Handle rate limits, flood waits, errors, auto-retry, and give me a simple report (how many added / failed / blocked). - Nothing else – no daily work, no group management, no finding users. Only this monthly adding task. - Safe practices only so the group stays safe (delays, multiple sessions if needed). Important: - This is NOT a one-time job. I need the same person for 12–24 months. - I will send the username list every month. You just add them. - You keep and run the script yourself – I do not need the code. Budget: 250$ – 500$per month (fixed price per monthly batch of 4000-5000 users) Or equivalent hourly rate if you prefer. Only developers who have done Telegram bulk member adding before and can work long-term (1-2 years). Please mention in your bid how many members you can add per day and any proof of similar ongoing work. Important note: I don't know pricing, If there is any issue about my offered price, we can talk
