Hello, I currently have in test / development the telegram bot @classifiedsBot, a bot that allows you to create and search classified ads (only the USA right now, but it can be any country). You can try it and see what you think.
This bot could be an innovative way for your business or that of your client, I offer to sell it including the domain classifiedsBot dot com and the development to adapt it to your business for 2,700, $ USD
Let me know if you are interested.
On the other hand I could develop the website of this project posted.
I can answer all your questions.
Thank you.
