website / php or asp.net + sql

I need a professional website bugs free coded by php or maybe asp.net this website must be easy to modify and translate to arabic language. this is going to be like predicting game for soccer, we will have different database. 1. for visitors who are going to sign up and play 2. for the data of the football games and fixtures, results, standing table. 3. for the workers who are going to work for this website. I have the rules ready for the game and you can translate it to a code, you must submit a trial for the game in a week or 10 days so we can check the accuracy of the rules that we made just in case if we wanted to change, then i will pay you for that. the website will have ads and banners, so it must support all the type of ads such as flash.
