Need Advise on Providers

I have a problem and I hope that some of you guys or gals may help me. I have been running into walls lately when looking for providers due to the fact that I am BLACK. It is is hard for me to see that is something that can disqualify me for service because I am not well endowed like the myth says and I am not a pimp or a bad guy in general. I feel as is I am an Ideal client very respectable and make them feel as comfortable as much as possible. The problem is that most providers do not want to see me or I read their ads and see no BLACK GUYS on it. I sometimes call and justify to no avail. And the women I do see do not give put me on the white list board so I may use as a reference.  
What are some advice that I may use to get me on the right path because I really want to enterain the SDASIANGIRLS.com but I need more references or credible ones.
