Marketing on a shoestring budget
There's an interesting article on Entrepreneur.com entitled "Marketing on a Shoestring" and subtitled "Don't have much money for a big-budget marketing campaign? You can still put your homebased business on the map." More than just being some low-budget tips, it covers some essential strategic advice that should be taken no matter what your budget.
I'm a big fan of doing things on a shoestring budget, and this article is a good starting point.
Years ago I wrote an article in Midnight Engineering magazine entitled "Product Promotion on a Shoestring; Low-cost Marketing Ideas for the Software Entrepreneur."
