I've done some freelance graphics stuff before, and I'm guessing that after the initial effort of constructing template graphics, the arrangement of the stuff on the page itself, and the inevitable re-make because the person doesn't like something about how it looks, it would be a $4 a page job.
But, I'd rather do it $3 a page than not at all, so how about this:
either $4 a page for the first game in a series and $1 for each page of each additional game in the series, 'similarity discount',
or $3 a page, straight, for any game.
Plus, since I don't know the moves myself, and I don't want responsibility to make sure I'm working from a perfect comprehensive list of moves, someone's gotta send me the move list info or a link to the info they want, for each game, and I'll put it to graphics. (reason is, those move lists get complicated! Some of those MK games had moves that could only be performed in certain circumstances, like 'has never used a kick this fight', had to be standing a certain distance, etc. and I don't know all those games well enough to do it without a resource.)
