Experts at modding oscommerce here!
you'll need to be a little more specific, though ... do you just want to integrate live USPS quotes to your shopping cart, or do you want multiple osc shipping modules, if so, what type, exactly? not that it matters for the bidding, really. will integrate absolutely whatever and however you want it. I have mentioned 2 days to deliver, but this can be done in a few hours once we get started and have all the details about what you require.
If I'm working on this, I'll throw in two free banners ads you can use promote your store - a $50 worth free gift!
Thanks!
