CS-CART Add-On/Mod

Hello. We need Mod build or Add-On for CS-CART This add-on is a Bard that show a percent when uploading images. (I know CS-CART has this option already but not with a bard that shows the percent uploading), After our client selects the product and paid for it they need to be able to see when uploading images what percent they have upload and a message that tells them that they are done uploading the images. For Example (Your order is Complete Thank you. This website is going to be for a printing shop. Business Cards Postcard Etc. If the client select one side then they will get one field to upload the image or if they select two sides then client will be able to get two fields to upload images. Formats: (jpegs, pdf, tiff, eps files, bmp). All images need upload to our server. Client need to be able to see images after uploading them and approve them with a option to delete image and upload new images if they are not satisfied with the images uploaded. Please keep in mind that clients are going to be uploading images of 300 DPI high resolution images, Need to keep that in the same quality or DPI in order to print them.. This mode or add-on to cs-cart needs to be easy to install by ftp. I need this option to be mobile friendly like the CS-CART and to work on pc and mac/apple as well on different explores like google, safari, internet explorer etc. We need all the rights for this mode/Add-On to do what we please with it. I'm going to be a re-seller of CS-CART and I'll be needing your assistant to install this mode on other sites of course that is going to be an addition payment for you. I have two more modes that I want to add to the CS-CARTS but I like to start with this one first. Thank you.
