Help on my first marketing Campaign

[Jonathan Guerrero]

I've decided to start my wholesale marketing campaign.  I want to begin next week.  My budget is small, max is $500 a month.  I have listened to the podcasts and have done some research and found that direct mail and online marketing is the most effective.  

How do I choose a zipcode in my town? I've done some driving and seen some boarded houses but how do I perform a correct comparison analysis on which side of town to target? Should I also get business cards? What about a website?  Should I build that first and then direct mail?

I'd like to know how many of you did your first campaign and the results you got.  I have some photoshop and a little web desiging skills so I'll be saving some money on that.
