CS-Cart Customer File Upload

Need to have a Mod build so that Customers will be able to upload images (jpegs, pdf, tiff files) to our server when they are on a product page. If they order Business Cards, they should be able to upload the images on the product page once they fill in the other options. The customer should be able to see a thumbnail image of the images they uploaded under each product they ordered. if they click on the thumbnail, the image should become larger so that the customer can see what they have uploaded. Should they need to change the image, an option should be given for them to delete image and upload another. In the event that customers does not complete order and have uploaded images, after 2 hours, the images uploaded should be removed. All this is based on using CS-Cart
