Looking for the right Shopping cart

Im looking for the right shopping cart for my photography business. I was looking into e-commerece but not sure if that will do everything I need it to do. I want to be able to add collections, products, ect. For a client to go into their gallery and purchase prints and products. Is there a plug in that exsits for this? Something similar to Photo cart for those of you who are fimiliar with photography and that shopping cart. Any help or suggestions would be wonderful.

Thank you 🙂
