Basically just like any other Art selling thread. Have samples of what you've done, your cost, what you will and will not write, and it's helpful to have a list of your favorite fandoms, as well as ones you won't write for if that's a thing. I often use 1 word: 1g, but I've also seen (on other sites), $1 for 100 words or something similar. Delivery is either AO3 or Dropbox or Tumblr, although I know some artists will give the fic in private and tell the commissioner to credit them if they post it publicly.
