Help replacing Evaporator/Heater Core for $$

I am getting ready to take on the task of replacing my leaking evaporator and probably going to replace the heater core while I have the dash apart.

Just curious if there is anyone in the area that has done this that would be willing to give me a hand for some extra $$. I plan on doing most of the work but I am not experienced at all working on a cars HVAC. Going about this using all the write ups I have found.

need more info on jeep , year , model , and so forth
