How to gather billing and shipping info without checkout wizard

Hi,

In our internet-shop we don't want to offer online payment. We want the customer to order and then leave billing and shipping info. New customers pay in advance, known customers are billed with the shipment. So unfortunately I can't use the checkout wizard.

Now I am not sure how to proceed. Best I would like to add a continue-button, that directs the customer to a page that collects the billing and shipping info. Another continue-button would then direct the customer to a review page, that combines the order info and the customer info, and on that page the customer could confirm the order.

Is that possible, without having to store any customer info in a database?

Or, is there a solution for ecart users, that don't want to use online payment?

I have to mention, that I am not familiar with SQL or PHP.

Maybe there is better way to gather all the information.

I hope this question is not too complicated.
