Custom Forms

Here is a simple problem or is it?
I want to create a form using outlook 2003 that gathers sales info from 4 sites at my business. We are not on a network so use email. I have been searching for a solution but cannot get the answer. when I create a form and send it the recipient only sees a blank form and no fields.
What is so difficult about this?
If anyone has the solution please help. I know about compose and read pages.
Thanks
Paul
