I have only had limited success promoting dating personally, but you may be interested in this
list of dating sponsors.
Since I have such little success, performance is based off what I can see those I have referred are doing. Each program is periodically re-evaluated and the under-performers removed, so only the best programs remain.
The thumbs on the left link to reviews of the programs in case you are looking for something in particular (payment methods, tools, commission structures, etc).
Good luck.
