I'd be interested in doing a custom, though it depends. What species is the char, and how complex is their design?
I'm able to do humans, anthros, and ferals, but I'm less likely to do a fullbody if its of the first two since I'm a little busy. But if the design is simple enough and easy to replicate, then I'd be glad to draw for you.
For examples, you can check

If you're interested, I'd charge a 2014 rare for a shaded fullbody, a 2015 rare for non-shaded fullbody, and maybe a late-2013 uncommon cat or dog for bust shot. They'd always be colored.
