Not ure what the going rate is up your way, but some local shops can charge up to $100 per hour plus $7 exchange per shim.
Like others have mentioned, it will less if you remove parts from the bike. I can give you a list of things to remove if you go that way.
So at around $100 per hour (worse case) 3 hours plus 5 shims it would be around $335.
Find out what they charge for shim exchange and hourly rate and a estimate time to do it for a better idea.
I tell you what, those shims are expensive. I had to buy a few kits and I didn't see much change from $400, but I now have it all cover. For honda CBR at least and whatever else they suit.
