How to focus efforts when door knocking for real estate deals

[David Hartoon]

Hi there, I've been door knocking for about a week now looking for wholesale deals. I'm looking to find ways to target leads rather than knock on every door. I don't have money to market to do direct mail campaigns (I hear they are pretty hit or miss) and I also hear that bandit signs don't work that well either (not to mention possibly illegal). So I don't have much option but to door knock. Does anyone know of any websites or tools or anything useful for driving for properties and knocking on the door. I'm looking for a strategy that makes sense.

I've partnered up with a local real estate investor who flips and wholesales deals. Although he mainly works the auction he has agreed to help me do my first few real estate deals if I can find some. Please help!! Thanks!
