Is zen-cart the ideal shopping cart for me?

Hi guys,

im trying to create a design resource store that works similar to istockphoto where users add and buy the items in the store. users are also able to determine whether there is a fee or FOC for their submitted items. at the moment i dont need any fancy features that istockphoto may have but just a simple user able to login, add item, provide files for the item, provide screenshot and details, and pricing under a category that will fit his item. then a user gets to login, view available items, download for free or go thru payment gateway and retrieve the download url for that item after payment's been made.

so since im new to zen cart and ive just successfully installed it, i was hoping i would get a definite answer to my confusion so i could start working mi arse off developing it. i'd appreciate if anyone could confirm my confusion :(

thank guys.
