I've just stumbled on
www.doubleyourdating.com which offers an e-book package for sale as well as a free twice-weekly newsletter giving tips. I haven't bought the e-book yet as I thought I'd check out the newsletter first. It's actually quite good and totally free of that misogynistic bravado that taints Ross Jeffries' course. Worth a look.
The approach seems to be one rung below NLP but effective nonetheless.
