AJAX Game Login & Permissions

I have a series of AJAX HTTP requests that I need help generating the Hash for. I don't want to make the exact HTTP requests public because that could compromise the account used for testing. In the game there is a file that contains the User ID and permanent key that is generated upon account creation. After that, all HTTP requests contain the BASE_URL/request_type?user_id=EXMAMPLEUSER_ID00001&signature=EXAMPLEskdjJOIIOHPIOHIOHNO. The signature changes depending on the type of request but is always the same for the exact same requests. I can provide working examples for this along with the game file (which most of it I can't read because I don't have the right kind a viewer and can't find one). I ask that anyone who bids to please message me so I can give you the working examples and the game file. After you get that, I would also like an example page put up so I can see that you have a working script. I would like the page to contain 2 input fields (1 for the user id and 1 for the permanent key). When I submit those fields, I would like it to display all 7 working http requests as links on the page so that I know the script works. -Page must be written in PHP with HTML/CSS only and I request that it contains notes explaining how you did it. -I would also like to know how you viewed the game file(if you did) to find out how to generate the hash(s), or how you generated the hash(s) otherwise. -I have a budget of $50-75 for this project. -All of this is for an IPhone game
