Customisation of Prosper202 PHP Script

I need customisation of this php script - Prosper202 ([login to view URL]) It is an affiliate tracking script capable of tracking via subids. The modification I would like to make is in the Revenue Reports module. The Revenue Reports module lets you upload a csv file from the affiliate network containing sub id's and commission amount of the lead. So each lead generated can be tracked to a specific visitor (and thus know the source, keyword & time of that lead) The affiliate network we use doesn't let us track sub id's, so this poses a problem. We are only given the ip address of each lead. Prosper202 lets us filter by ip address, so we enter the ip address of the lead into Prosper202, and the visitor that generated the lead is shown. It also shows the auto-generated, unqiue sub id that is assigned to that visitor. We can then take that sub id, along with the commission amount, and upload it to Prosper202 via the Revenue Reports module. I would like to automate this process. How I propose you do this is modify the Revenue Reports module of Prosper202 to accept ip address in place of sub id's. I would upload a csv with 2 columns - ip address and commission amount (instead of sub id and commission amount). I would want to retain the original workings of this module, so the mod would need to be built with that in mind (i.e present an option to upload ip addresses or sub id's) I look forward to your bids. Thank you, Rod Lynn
