Ecommerece Build w/ Facebook Product Catalog - Ongoing Work

Hi,

I would like to build an e-commerce site for a local store here in the U.S. I can send you UPC / SKU info and you do the rest.

I would like to create product catalog feeds for Facebook on my store fan page.

I would like users to be able to schedule pickups at the store so we don't ship the product. They can receive an email or go throughout checkout to either pay in advance online or pay in person at the store. When they pay in person there should be something they can click to trigger the inventory level to go down.

Since I am constantly getting new product in stock this would be an ongoing job maintaining the inventory to ensure tracking is working and adding new products.

Having some idea of Facebook and Google shopping feeds is a plus.
