creating a ecommerce application, how long did it take you?
I don't seem to like any .net ecomm app out there and was thinking of rolling my own.

My requirements are pretty straight forward.
1. only u.s customers can purchase
2. tax in only 1 state
3. simple category structure (2 levels)
3. products don't have any variants, unique by the sku

It *seems* there really isn't much to it.
I already have the design, just need the backend work so things like:

GetCategories
GetChildCategories
GetProductsInCategory

Cart (addItem, deleteItem, update, select, create)

Then I have some user account work, and then listing past orders for a customer.

Then in the admin side, listing orders by date range, listing order items.

Checkout

Has anyone ever done this before? How long did it take you? 
Am I crazy to roll my own?
