How much does commissioning you for “___” cost?

It highly varies on what is being commissioned. I may list a general price range for some things, but that’s not to count the actual total cost and only to be used as an estimate or starting cost. Otherwise, I may have a commission section set up with the appropriate price ranges for various items/services offered if it’s a fixed type commission.
*Please note that I will generally post somewhere if I’m open to taking commissions. Usually if I do take commissions, it’ll be limited to a certain amount of slots at a time.
