Hi there.
I presume the mistakes in your ad are to see if we are paying attention (gamer, knead, cotent). The page you say is ok is not ok. Everything needs to be rewritten correctly and explained a lot better. You also need a snappier catchphrase than "Our success comes from teamwork". Try simply, "Success from teamwork". I can give you US or UK English. People are bidding very high on this project, but I don't see much content. If you can give me some better explanations of exactly how your business works, I'll be able to sell you with expert copy-writing. Please contact me immediately while I have space in my schedule.
Malcolm.
