How much will replacing bolts on a Honda Civic cost?

I have had my car in for a week for a series of problems, and it appears that 2 of the main problems are possibly a result of a very unreliable car shop not putting the bolts back on when they did a brake job. It cost over $1,200. 3 out of 4 "rotors"? are missing a few bolts, which explains the grinding sound I'm hearing. How much will the price be? This is a very reliable shop due to the owners being friends with my mom for years and they're very honest.Edit: The car shop that discovered the problem is the reliable one. via /r/cars http://ift.tt/2t78Inf
