Wholesaling Marketing

[James Kramer]

So I have spent a lot of money to get a specialty 6 x 9 postcard sent out and using yellow pages for people that want to sell. I sent 1000 out two weeks ago and have not received a single call and I am told I should b getting a 3-5% call back. Mailing criteria is: homeowner and low to middle credit score. Any ideas why I am not getting any calls for something that is professionally done? I am thinking I can narrow the mailing criteria better, but not sure how. 

Thanks
