Through kofi, you can access the commission listing on the commission tab. I sort my prices depending on length. You can also click on the gallery tab and see the images of my terms of service as well. When you access the full commission list, and order whatever you'd like. I'll get a notification that you placed an order and then I'll contact you via email. Also, there should be a text box for you to write all your ideas down and let me know what you would like to see.
