It's actually not that bad.
Here's the issue with what you want to do.... it will in all likelihood cost you a lot more than the game is worth, to restore it if you let other people do the work. Unless you have a personal attachment to that specific game/title, why not tackle the job yourself? Most of the areas on that game that need touch up are pretty easy to do -- they're mostly in black. You could even take a marks-a-lot to it and it wouldn't look too bad. In all likelihood, if you want a really nice-looking game, it would be cheaper to put feelers out for a better quality version of that game, which isn't impossible to find. (a lot of pinball purists don't like those hybrid pin/video games and as a result they're not expensive).
The costs on that game are going to start to add up... the pac lite matrix lights are not cheap either, and there's 50 of them in the game. It's definitely an involved project getting that game working, but will be very rewarding if you do it yourself. Personally, I love the game. It's a lot of fun.
