I have this posted on my FA as well.

Hey guys.
I'm in a bit of a pickle right now.
I need to make at least 300$ by the end of the month so I can eat, my snakes can eat and so I can pay rent next month.
I'll do any of my art work for you for this discount, no exceptions. Multiple pieces too.
Message me what you want and I can give you a quote/discount price.

Or, if you want to help but don't really know what you want, list what you're willing to offer and I can tell you what I can draw for you.
