Lower intake gasket is around $50, and they usually don't go bad. SC gasket is about $8. If you get the parts, I can do it pretty cheap. A dealership will charge a lot for labor. It's not a hard job to do, but a lot has to come off to get to it, so it's fairly time consuming. There are other things involved, so you need more than those two things, but it's mostly incedental amounts.
So, this is what you'll probably need:
LIM gasket $50
SC gasket $8
PCV valve $4
Coolant elbow $15
Oil change and filter $price depends on what you use
Top off coolant $5.00?
As far as me doing it, you'd need to drop it off. It may take several hours to do if I run into anything (and you remember what can happen even with a simple job: AKA Wheel bearing replacement). I'd estimate about a 2 hour job normally.
