A Website similar to justanswer.com

I am looking for a someone to build a professional high quality ecommerce website as good or better than [login to view URL] and healthcaremagic.com. I prefer the business model of healthcaremagic but with all the question categories a la justanswer.com. The website will need to have multilingual capability. A NDA will be requested and all the site's code will be required.
