I'd say $1000 is pretty high and likely is mostly labor. You can almost all of your bike maintenance yourself for a small fraction of what it costs at the bike store and if you are halfway handy you will probably do as good or better.

$1000 would probably also include things like cassettes, chainrings, chains and brake discs. Depending on the system on your bike this stuff can get quite expensive.
