If you really want commissions, try writing yiffy stories, and THEN offer commissions.
But well, that's the easy way. A way which is imho quite uncomfortable...

I actually have wrote a few yiff ones, http://www.sofurry.com/page/233308/user, this one in particular I'm really proud of. one of the first commissions I got paid for, had two before that, guy messed me over. He was cheating a lot of people. Contacted the admin, no longer a prob.

Ooh, ok. My mistake: I have my filter turned on. XD
I thought you didn't write yiff. :P

GL!!

Usually I don't. But for commissions I will. And honestly that turned out really well, posted it on here as well, don't usually post here though due to i have to transfer to a whole different doc type, find it, and then post it. Not fun. But Rowing Revenge received three Cums which apparently is pretty good.

Good for you that you know that three people came while reading your story...
