Anyone want a referral ?

Have been promoting affiliate programs (well one mainly) for a couple of months now, and have managed to turn it into a full time income. But I'm looking for more than that, and I seem to have plateaued. Also very nervous relying on one program incase it goes belly up.
So, looking to join new programs, but before doing so do any knowledgeable people here want me to sign up under them ? A: would be a shame to waste the extra commission, and B: If you can give me some tips then you'd benefit from my efforts..

What kind of programs are you looking for? What do you do well with?
