528675 AJAX / jQuery project - additional feature + fixing

Hello, We have one special application and we would like to add a special feature on the checkout page. It should work like this => When we type in name of school in the form field, it should search trough the database (tbl_schools) and list all matching schools if any (pretty much autocompleter), WHILE on selecting that result, it should fill out rest of the form fields with data from database. I think this is really easy job for someone who knows AJAX/PHP/MYSQL NOTE: autocompleter is finished, it's not working, because there is some other AJAX code on same page and perhaps it's interfering or somehow blocking the autocompleter code, which is using jQuery library etc... We will select a programmer in next 12 hours. We expect that work is delivered in max 6 hours AND by biding you agree to deliver the work in max. 6 hours!
