They are way more that that.

Sounds to me like the service advisor quoted you the price for replaced the engine drive belts i.e Alternator / AC / Pwr Steering.

Timing belts usually run bewteen 400-600 bucks depending on what level of service you want.

Most do the timing belt , water pump, tensioner and thermostat and at times the cam and crank seals as it's easier to do them all at the same time because it's all apart.
