A great site for this is
Hundreds of Free Articles on Meeting, Attracting, and Dating Women - Tips and Advice. Do a little searching in the forums and you will find guys who have participated in 'DJ Boot Camp' -- it involves gradually overcoming approach anxiety. You will have to sift through some crap to find the good stuff, but it is there.
Also, read the DJ Bible @
