perfect
Wow. You beat me to that one.
That's exactly what I do = custom art for people. Used to draw/write comics for Marvel years ago, now I like the net art thing.
I'm waiting to invent a cooler name... one hasn't hit me yet for what I like to do. But yours, though not an exciting name, is immediately recognizable as providing a valuable service.
I'll keep thinking on it, because I'm a sucker for way cool names instead of this meat-and-potatoes kind. May still PM you in a month or two - but I don't think you'll have any problem selling this name for more than I'd offer, even then

For now, an appraisal:
Immediately recognizable as valuable, clear keywords, desirable meaning to any artist in business, so -
reseller = med/hi xxx
end user = low, poss. even med x,xxx if they think it's perfect.
