jQuery Autocomplete - Modify to get results from MSSQL database

Hello I have 2 websites, 1 uses PHP and the other .NET I am using a jQuery autocomplete script currently in the PHP website. The results data are pulled from a PHP file using JSON I think. I also have the results data stored in a MSSQL database. So I need help with 2 things... 1. I need to use the autocomplete script so instead of pulling the data from the PHP file, it will retrieve from the MSSQL database. 2. Use the autocomplete script in the .NET environment and retrieve the results from the MSSQL database. You must be able to work with me to make the autocomplete as quick as possible. This is a very easy project for someone who knows Javascript, PHP and .NET with experience in MSSQL... Job needs to be completed today. Cheapest and quickest will get the job. PMB me for the actual autocomplete script I am using. Thanks
