Monetize the questions and answers and also show questions to people based on location

I have a plugin anspress that i need to monetize the questions and answers… and also show questions to people based on location, category of interest.

The admin has to have the ability to charge to post a question and also allow the user to post the question, then choose the best answer. After posing the question he/she will pay money via paypal/stripe and then when he gets the answer he’ll choose the best answer and the money will go to the best answerer
