need a script for wholesale phone case design selling

We have started a new business to print phone case and sell wholesale. Now we need a script. We should upload bulk designs very frequently and customers should select phone model first and then they should select designs very fast and bulk. The result can go to basket or just a list and e-mail is also ok. The key point here is that we should upload too many files at once, and the customer should select designs very fast.
