Around here, a couple of calls to the Volvo shops would find you a good used window glass for $25. Anywhere near Connecticut?

It's a pretty easy job to replace it yourself. The hardest part will be vacuuming all the glass out of the door....
you can do it with only basic hand tools. Couple of screwdrivers, nothing more.
Going to have it done or do you want instructions?

I would guess a shop would charge you 1.5 hours + the glass (used being the cheapest way to go). So figure $90 + the glass. ($20-50? depending on your local junkyard availability).
