Do you mean 2000 rpm?
Is this a 4 cylinder engine, if so it is non-interference.
What was included in the timing belt package?
Would assume the shop check the exposed belts such as power steering and alternator but would recheck.
Timing belt replacement being common, check with other shops for lower prices. The Camry is well known, any competent shop should be able to do the work. $700 is in order with Toyota dealer repair costs. The belt may cost $20-40, a kit $50-90, the rest is labor. A competent DIY car owner should be able to do the job in 3 hours, a shop a couple of hours. Shop around for prices.
