Brake Caliper Help (Update #2 with picture of charges)

First of all I had pads replaced and rotors turned in January of this year. I noticed a pulling/vibrate when I pressed my brake today. I pulled over and got out to inspect. The front left tire/rim had smoke coming from it and I could smell burnt rubber. I drove directly to a dealership. They told me that it was probably the caliper. They said they would likely need replace both calipers on the front end along with new pads and rotor service. I am a stranded driver and don't want to be taken advantage of. They will likely tell me that they won't service just the caliper. They will need to do everything they can find so I don't wreck and die. Mechanics of the OB unite. What should I expect? TIA!



Update:

They told me they were going to check first thing this morning to see if they could get the calipers. The guys exact words were, "we won't slap anything on the vehicle without calling you first". I just got a call saying my vehicle was ready. I asked them how much damage was done and the lady said $680. The service manager told me it would be it would be $500 max yesterday. I told her to have them take everything off and I was going to take it somewhere else. She said she would have the service manager call me. He called to apologize for no one calling and said that both rotors needed replacing. He went through the normal "I'm trying to help you" talk and worked it down to $580 for 2 new calipers, new pads and 2 new rotors. I know he is still making money. Are they still taking advantage of me?

Update #2:

I went to pick it up and asked to see the parts. The old rotors were both in bad shape. Here is a picture of the description of service and parts:
