in my opinion it is not easy to find a good bounty development, maybe a few weeks ago I was just like you, confused looking for a good project with the development of the bounty and yes in the end I got information from friends here and after I thought I thought it was good enough to do,
I think you are misunderstanding what the OP is looking for. As @slaman29 correctly said, the OP is looking for bug bounty services. There are whitehat hackers who work with debugging different things and they help in development of a project by making sure it is bug free on different aspects. We are used to the word bounty as a payment for promoting a project but that is a different type of bounty.
As for the OP, there is less chance of you getting any good tech people here, better to ask on a freelancing website or contact a tech consultancy firm.
