Froogle file generator mod

We have a program to generate a text file for froogle from a classifieds script but we need to have it pull in information from dropdowns and radio buttons as well. The information from these are stored in a text file and the infrmation is retrieved from relative the database field by their position on the file. eg .1,2,3,4,5 etc. No time wasters or amateurs please as we haver been messed about a number of times in the past. Before payment is made there must be AT LEAST a functioning demo.
