I would like a checkout process just like this one here:
[url removed, login to view];spid=VQOZZZ&signup=true&sbid=dKTFH&cids=ZZ34TZ,0&spids=VQOZZZ,71&spoptid=71
(See each step of ordering, paypal, credit card separate, etc.)
There also is an admin area showing the pending orders, cancellations, shipments to send, etc.
I know there are man shopping carts out there and will make a preference for a bidder who can show me an existing shopping cart that you will just install on our server (and/or customize) to make it just like this process.
