Custom Cart for 1 product

I need a custom cart for 1 project similar to www.wearrshare.com. Users need to be able to log into the site with facebook only and the user can select photos from their own files they have uploaded to facebook and add up to 6 to their bracelet. After upload I need a image that will show the images uploaded in the bracelet so users can see what it will look like when they receive it. I also need a 3d version that rotates for the user after purchase. I also want users to be able to share after purchase to facebook the image or a link to the 360 view of the product that was purchased.
