Interesting idea, but it seems that everyone has to pay, for every interaction. Plus the answers are not visible.

If you put this interface to how https://soldirac.com works, you'll have a winner
The payments for user signup and post questions and answers is to prevent spam and keep a quality filter.
The answers should be visible after you pay for them.

Check the user rating of the seller before you buy.
Then, after you buy, if the answer is nonsense, downvote the answer to punish the reputation of the seller.
