309458 Need a Q&A site built

I need a Question and Answer site, with customers asking questions and paying for answers. There is a similar site ([login to view URL]), but I want it to be more flashy -- more visually enhanced, but with the same features-- for people to pay and be paid from the site. The site will enable customers to sign up/log-on and ask questions of certified professionals such as doctors, lawyers, dentists, psychologists, psychiatrists, mechanics, bank/loan officers, credit repair experts, veterinarians, etc... there needs to be question/answer forums that are visually inviting. Experts will be paid by the customer so I need a pay option and I also need to be able to accept credentials and/or verify those from the site (?)
