That's a bit steep for the "friend" rate
Add in Honda parts and that's about what you'd pay for the job at a Honda dealership (around here - belt, water pump, and the other common bits).
This job is done on the ground, not on a lift. Well, I suppose if one has a lift they might use it a little bit but you only need to remove one wheel and the inner shroud, which a lot of people just do from the ground (floor jack). Either way, I can do all the basic maintenance (fluid changes, etc) and then some (gasket replacements, brake calipers, etc) but I'd pass on a timing belt. Get a gasket wrong, it leaks. Do something wrong with a brake caliper, it simply won't work (binds up, won't bleed, etc), but you should discover this before driving away. Do a timing belt wrong - when you turn that key and it's wrong, severe and not-repairable damage can be done.
