Nope.

Honestly, if you’re just looking for the touristy stuff, the less expensive route, you really don’t need a guide. I would also recommend not staying there overnight and do a day visit from Nice.

It depends on the amount of money you want to spend.

Probably too late for you, but for the benefit of others… check out other sites similar to 43Places, such as VirtualTourist and CouchSurfing. Find people with local blogs. Befriend a local or expat, then be presumptious and ask them to show you around. Alternatively just hang out at Wayne’s bar in Nice. (And I agree with butterfly, stay in Nice.)

This has happened to be me before and I’ve given ‘tours’ along the coast on my scooter, but I don’t live there any more :(
