CRE Loaded file upload programming

We have an existing CRE Loaded site (6.2) that is in need of new solution for our clients to upload their files. Our current system redirects the client to an upload page after they have completed their order. There are 8 upload boxes, the files are prefixed with the order number. We would like to "modernize" this part of our site with the following features. 1. The number of available uploads would be based on the products that have been ordered and the product options. As an example, if the client ordered 1 business card, the upload page would have two upload boxes: "Front" "Back". 2. Each product will need to have an option for the number of downloads with corresponding names. At most, a product could have 5 uploads. My suggestion would be that the product would have 5 "drop downs" to create the upload files. The drop downs would have all of the possible file descriptors (front, back, front mask, back mask, etc etc) The first choice would be "Not In Use" and would not display on the client upload page. 3. The upload page would have a list of the products that were ordered, product type and job name (our site allows the product to name each order. As an Example: {Product Name 1} {Job Name 1} Front: ___________________ Browse Back: ___________________ Browse {Product Name 2} {Job Name 2} Front: ___________________ Browse Back: ___________________ Browse Front UV Mask: ___________ Browse Back UV Mask: ___________ Browse 4. When the files are uploaded, the will be prefixed as follows: Order Number_Job Name_FileType_File [login to view URL] or: 23456_BobBusinessCard_Front_ClientsFile [login to view URL] 5. The files are upload to our site for retrieval by our staff. 6. The file names are added to the order comments. Notes: I would like for the clients to be able to see a progress meter. I would like to let the client know when their upload is successful I do not expect you to reinvent the wheel. If you know of a good commercial program that w can purchase and modify for our needs, I may be open to that. PLEASE be sure you completely understand this project prior to bidding.
