Well parts will vary depending on the size of the cam and how many things you feel need replaced. The absolutly needed parts are the cam, pushrods, valve springs, and gaskets. The springs can vary some based on the cam, bigger more aggressive cams will need stiffer somewhat more expensive springs. Then there are the optional parts that would be a good idea for a higher mileage car or for added piece of mind, oil pump, lifters (but would require head removal), timing chain. If it were me I'd put a fresh timing chain, and oil pump in as these are very important and not too expensive parts.
Cam $400
Valvesprings $200-$400
Pushrods $125
Timing Chain $125
Oil Pump $125
Gaskets/Fluids $200+/-
As for labor you're on your own, I've never paid for work. This is all off the cuff so its just meant to be close.
