What would you propose if you would make a simple login/portal for selling products to architects world wide? It looks like Paypal have a good global shipment setup, what if its used together with osCommerce? But still open for options. Text can all be in English, just checkout and be able to pick the country you from, and us to be able to configure the shipment cost.
No Fancy, just clean design and minimalistic. Just add products and checkout. Its not open to all, need a login.
We will take care of the shipping details and add the items etc. Just need the design and the configuration done for the hole world.
