want to have cart in place, but not payment checkout. how?

[Guest]

i want to setup os commerce so that a customer can check off the products and quantity that they want and then submit that order to me via email, BUT they do not pay at that time. instead, i take their order form and process it in my office at a later date.

 

also, i would like them to be able to easily print the screen for their records.

 

i am completely new to os commerce and can use any help that you can provide.

 

thank you.
