Sell files

Hi all,

I want to sell file (for example in PDF) obtained thanks to the files contained in the cart.
So, the customer choose files (which will be in its cart and then after some postprocess we create our "product".
Is there any way to do that ?
I've no experience with drupal commerce ( a little one with ubercart).

Thank's for help and suggestions,
