Herb Chambers Honda of Seekonk MA has a timing belt coupon https://www.herbchambershondaofse...ervice.htm
It's $349 + $89 (water pump) + $49 for other belts. You can add gasket and refill radiator for a few more nominal charges. Should come to around $550 for the usual "timing belt package" you can compare to other dealers. Maybe you can price match to your own dealer. Add $100 for V6. My own dealer wants $900 for this same package.
I've used them in the past and they seem to have a good service department. Coupon is only good till January 31 if they don't renew it.
