Translation of Business Terms (German to English)

I require my companys German "Allgemeine Geschäftsbedienungen" (AGB) to be translated clearly and correctly into English. Its a total of 4 Pages which need to be put into grammatically correct english. Price is fixed at 50US$ and the whole project should be done by a professional in around 1-2 hours. I will only accept someone with excellent recommendations and speaking english as mothertongue. Correctness in Terms, Language and Grammar is important as i will only pay for the utmost excellence.
