Im using PayPal as a check out for one product, and I need the client to fill in about 20 fields at check out. PayPal doesnt support this many additional fields, so what is my best option?

I dont really care if I have to install a shopping cart, or if I can do this with a custom form that then emails me the results as at checkout, however keeping it as simple as possible will be good, as I only need this for one product.

The information in the form can be either transfered through to PayPal, or emailed to a specified email address, or exported to something else, doesnt really matter whatever is more secure.

Any ideas?

I've got to ask 20 fields ?? can't this be cut down some ... ie do you really need the address fields as you'll get them off paypal anyway... could we see the site / form in use at the moment ?
