Hello,
I am experienced building different type of bot from simple to very complex, I think python would be the best suited for this project as it is lightweight and fairly simple to read, I built some kind of scaper in the past that I think are really similar to what you are looking for.

Also, I have no problem receiving payment after you test the bot is in accordance to what you specified or simply using escrow, I would be glad if we could discuss this further.
