I suspect you and the shop have had a comunication break down. The thermostat would never come close to that kind of money and its probaly better chance the overheating issue could be another problem all together. Cooling fan issues are not uncommon and then the cost that you was qoated may be in that range if its a cooling fan issue. As for the prcedure for the thermostat is listed below.

Remove upper intake manifold.
Partially drain cooling system below the thermostat level.
Remove upper radiator hose from outlet connector.
Remove coolant recovery system hose from outlet connector.
Remove coolant outlet connector bolts.
Remove thermostat assembly, and clean sealing surfaces.
