Clips4Sale.com (the same site that offered LiLo $50,000 to pop some balloons) just sent Nadya Suleman a letter -- obtained by TMZ -- offering her $20,000 ... and all she has to do is wash her hair on camera and put up with a little tickle torture.
The $20,000 can easily cover Octo's $7,500 in back mortgage payments -- and we're told that might just buy her extra time to come up with the $450,000 she owes on top of that.
Coochi-coochi-coo.
