I need something that can be done on a part-time basis without having to pay a buck. Any suggestions?

There are 2 kind of businesses online:

1. By having your own good product;
2. By beeing an affiliate for a program

Affiliate programs is the most simple since you don't have to worry about: creating a product, outsourcing your market, shipping, packing, no major expenses, no need for other employees and no need for "fancy websites".

PS: I almost forgot. There is no such thing "make money with 0 investment". If you don't believe me you'll surely see it with your own eyes.
PSS: If $5 in three months is your idea of making money online, than this is my bad. It must mean that I didn't understood the question. :) There are some sites like PTR:
