Advice on a good marketing strategy? Letters/Postcards/Website?

[Rajae El temawi]

I have opened a website and got most of it up and running and trying to get myself noticed.  

But i know this will take a long time and should not be my only source of leads.

Looking for a good place to get good lists and how do I split them up.  Do I just buy lists from YellowLetters or use County records or RealtyTrac?  

I really need pointers on this before i start dumping money into lists that are either too old or have no potential.
