Product Purchase mod needed with file upload

Product Purchase mod needed with file upload, with the following features....

1. For each item purchased, I need to allow the customer to upload a file. Say you are selling mounted pictures, customer can upload the picture, choose the frame size and checkout. The file is associated with the line item and named accordingly.
2. I also want a comments field to be attached to the each item purchased.
3. I need the customer to be able to purchase the same item many times, with each one showing up as a separate line item.

PM if you can help...

Could I ask what add-on you found and where it is?
