I need to archive the following, whats the best way to go about this:

1. Need a one click checkout button for products so that a customer can click and be taken directly to the checkout page (bypassing "add to shopping cart").

2. On the checkout page user should have ability to select from 6 shipping methods (all custom, no ups or usps), enter shipping and billing information and check out.

Ive tryed fast and easy checkout for zen with no luck. I simply want to streamline the checkout process and only use zen cart as a means to pay for product.

Sample:

Something similar to the above this is what Im looking to archive, is it possible?
