Its difficult to say without knowing the condition, but it does seem like around 2.5k per pin is a little low. It's business so the dealer needs to make $$$.
Games in demand like yours seem to FLY when posted on craigslist in our area. I would think you could get more money if you just sold them on your own. You could get 3k a game easy, if not more. You can specify that you can't help with lifting or transportation so you wouldn't have to worry about that end.
You can just sell to a Pinsider. Looks like Herg beat me to the punch though.
Good Luck to you!
