Where can one find pricing for garage doors?

One can find pricing for garage doors from many places. These many places include, Home Depot, Lowells, or the website of any store that specializes in garages.

Sinse most of the times you need to hire one for the installation separately, I suggest you call your local garage door company. They usually offer free estimates (insist on it in case they don't), so you can get a pretty good deal altogether. You will also enjoy the warranty for the installation, door, parts, etc.
