Unless, of course, you are planning to do a big google adwords campaign or other paid advertising.  

You cannot advertise "No Section 8 Accepted" or "Section 8 Do Not Apply."

Curious about getting marketing sponsor's from company's not related to real estate but can benefit from the advertising?  

. :)Quick ideas with "$0": Create Bandit signs (at your own discretion), Utilize BP marketplace (Plus & Pro Accts) to advertise you are looking for Cash Buyers in your area, Attend as many REIA or meetup groups in your area to build your network, "Drive for Dollars" and look for distressed and vacant properties & do some research in public records to mail the owners, search craigslist FSBO...

To do 25 flips you'll need to run advertising.  

Hi BP Community,I'm interested in a property that has advertised seller financing.

The REIA just north of me supposedly teaches "wholesalers" how to get written permission to "market, advertise, show" the house once under contract.

Most people don't advertise their problems.

Your post reads just like an advertisement, something I might see on late night TV from some puffed up guru.

I use Rentometer 1st and then dig into Craigslist to see what people are advertising similar properties for.
