Inquisition

I need to build a website. It would be a basic ecommerce website except it would need to include a "unique" thing. Basically when someone ordered, I would need to get an email invoice of what they ordered and attached to the email would need to be a series of text files(information pertaining to the order) that the user would input when placing their order. I'd also need to have the option available to attach a file to the order. I'm sure I can figure out the scripting for this, but I'd prefer to be able to just use an online template.

I would like to use a credit card processing service that is not paypal and a traditional shopping cart. I don't trust paypal and I don't want my account being locked up randomly or for a BS reason. I'd also like an account login thing as well.

If you know of any good services that aren't too costly, post 'em up.
