Amendments to casino games in Flash/ActionScript/PHP

We have 2 casino games that need some amendments in order to get them working properly. They are made with Flash/Action Script, using a PHP script for the server side. I will help all I can with instructions on how the games are supposed to work and make myself available as often as possible. The winning bidder will need to sign a Non-Disclosure Agreement. Please only bid if you are experienced with Flash/Action Script/PHP, as I do not fully know the difficulty of doing this job. It's simple enough to explain, but I have no programming experience. I also have some miscellaneous work on another game, which should not be difficult at all to an experienced programmer. This project is very urgent and should be treated as a #1 priority. I have set the budget as $100-300, but if it takes longer I can exceed that.
