How much is a new motor for an automatic pool cover?

My automatic pool cover motor would hum, but nothing would happen. I called a company out and they said the motor for the pool cover needed replaced. The part was an APC-KA0056 for a new Motor Autoguard w/harness, and it was $885. They also installed a new key switch assembly w/o junction box for $116.25 (part # PCS-IN1104). The service call was $30 and the labor rate was $110/hour for 2 hours. Is this bill high? I can't seem to find the price of motors online.
