48226 Addition to current php script

I want to add to my current php script located at [login to view URL] the option to offer downloadable products which should work as follows: * Store owner has a separate form to add a downloadable product which allows them to upload a file in : .zip, .rar. .doc or .pdf file. (Other fields will be the same just the extra upload field that will upload their file to their personal directory) * Will also need a separate form for editing downloadable product * Store owner can set preferences, for example, # of times a user can download or time frame based * download url for customers MUST be hidden, customer should NEVER know exact download URL! * Other suggestions you can give! Payment only after completetion and testing on my server. PLEASE do not bid if you cannot complete in the time you specify, I dont have time to waste on games and waiting around for nothing.
