He wants "an equation or a name", not the Mona Lisa, why on earth would he need the best artist in town?
I suppose everyone knows he's in Vancouver? If you were in Victoria, I'd suggest Ascention Studios. I'm new in town but met a couple talented guys that work there. They do real art however, and are not hard up for business, so unless you were looking for some real flare in the equation/name (around $300) they may prefer you take your simple $80 item to someone else. Either way, they would probably treat you real well if you didn't come off as a whiny tool.
