Add file upload option

Hi. I am considering Marketpress for a client - It's not on a multisite install.

The client runs a printing business and I need to integrate an option for customers to be able to upload the artwork files once they have placed their order and then for the client to be able to easily receive/download those files.

I was planning to use the paid for YouSendit option that I can integrate into the site - but thought I would check if there is an option within this plugin - or if you have any other suggestions that would make the process easy for the customer and my client.

Thanks for your help.
