May be, commissions Tier? (Patreon)

Thinking of adding an option to some Tier (or a new Tier) for commission access.

Of lower price and decision of accept or not accept. Because I do not need commissions for cash now, I can do those for fun at times, but still don't want spend days drawing "mah angel-demon wolfie with five different coloured eyes and immafiring mah lazer from nose and draw his pawz omglel!!1!1" (nothing personal...)

Perhaps, it will be some basic low price with "pay what you will" style... So everyone are happy - me as doing orders that I enjoy and not sacrificing time, others - getting what they want and not bumping into cost issues...

Would appreciate opinions for feedback helps tweaking overall services.
