Depends what you're advertising and what level you want to be remunerated.
Word of mouth is fine, but as Zeke says, if you need to be billing $X per day, this is unlikely to feed it.
Best bet is to seriously think about the $X per day amount, what sort of customers are going to provide that level of billing. Then start learning about their habits and where they are looking for various things, in your case photography, then work out a strategy for how you're going to get yourself in front of them. If you want high paying customers, you're less likley to find them in the local newspaper, they're looking for a more premium focused product and that's where they'll look, and so forth.
