So I started taking commissions last month. I started off with just my Patreon patrons as a test bed, to see how I handled things. It went well. Commissions break down into one of two categories:

Short (5-10 pages but absolutely no more than 15)
$10 minimum, tips welcome
2 slots in a given calendar month

OR

Long (15-30 pages but absolutely no more than 40)
$30 minimum, tips welcome
1 slot in a given calendar month

This is to help me maintain a degree of control over my production schedule.

Here's how it works.
1 - You get in line for a story
2 - We talk about what you want
3 - I write up some notes including a skeleton (a bullet-point list of events in the story)
4 - You read over it and approve it
5 - I write the rough draft which gets posted to my patreon, on weasyl tagged as 'friends only' and sent to you to read
6 - You let me know if there are any changes that need to be made (within reason, the notes help keep this from being too huge)
7 - I make the appropriate changes as well as proofread/edit
8 - Finish product is delivered and posted publicly on SoFurry

What I'm mostly known for:
Vore (various forms), Unbirth, Hermaphrodites, Pregnancy, Male Pregnancy, Cum Inflation, Hyper, Gender Transformation, and other things

I reserve the right to decline a story idea. There are fetishes I will not write about. This is only a short list. If you don't see it here, ask about it. At the very least, you'll find out where I stand.

WILL NOT WRITE ABOUT
Scat, Watersports, Blood and Gore, General Cruelty

I'm thinking about other forms of commissions, like a your-character-here style thing. Keep an ear to the ground for coming updates.

I only accept payment through Paypal. Details on that will be given as needed.

If you're interested, email TheTreetopInn AT gmail DOT com with a brief description of your story idea as well as preferred methods of contact. Please put 'commission' somewhere in the subject line.
