I would suggest looking at craigslist. Most landlords are frugaland advertise in the most efficient manner.
Another method is to drive around an area that you like, and call on for rent signs.
For section 8 housing you might want to check with the city or county office that has jurisdiction for housing and neighborhood services.
I hope you find what you are looking for.
