Telegram Bots - API, Python etc..

Hello everyone, I'm looking for a developer for long-term collaboration. I have several telegram groups and channels through which I offer my products and sell them by bot. What I'm looking for is: A developer who has the following knowledge, API, Google Sheets, databases, Python as a general knowledge in the field of telegram channels and groups. Long-term cooperation is particularly important to me because the existing bots are to be optimised and expanded, improvements and new functions are absolutely necessary and important, especially in my area of activity! The payment is therefore fuelled as follows! The developer is involved in the success, there are 0.15$ cents per sale, the monthly sales are currently approx. 2000-2500 These bots are about product mail and shopping bots, but also bots for dropping and importing products from Google Sheets. The expansion of the countries in which we sell is to be expanded to include the USA, CA, MX, and India in addition to the current UK, DE, FR, IT, and ES, which should significantly expand the amount of sales! In addition to the knowledge provided, also important! - To contribute ideas - To show and realise possible opportunities for improvement - Prevent and recognise errors I'd be happy to hear from you!
