File Upload Module

I am looking for something so that I can upload more than 1 file at a time in my SmartSection module. I put about 20 pdf's a day & it is a hassle doing it 1 at a time. Is there anything out there??

Buyers Module

I am looking for something so that customers can buy using PayPal and receive a username/password to get into certain parts of the site, depending on what they purchase (files). Any help without me having to purchase modules from someone??

Thanks for all the responses.
