Hello. Welcome to Just Answer. Please allow me to assist you by discussing your request in detail; thanks. What engine do you have, 4 or 6 cylinder?
I see that you have previously opened a question identical to this question. On the 2000 4 Cylinder Camry, you can expect to pay $110.24 for the water pump (Toyota part number 16100-79185-84).
The timing belt should cost $40.97 (Toyota part number 13568-09041)
You should expect to incur about 4 to 4.5 hours labor times your areas average labor rate.
In my shop, the total charges, with coolant and tax, would be about 650 dollars
