I would do em yourself if you have somewhat of an idea of what you are doing. They really arent that hard to change, even if you do start breaking plugs. I did mine and I have done them at work and if you break plugs the only tools you need are a long punch in case you need to push the porcelain down, an easy out (don't remember what size) with a sharp edge that is slightly modified (the bottom side needs to be ground down about 1/4 to 3/8" to fit the sleeve of the broken plug properly), and tap socket that is the right size to fit the easy out, and a long 3/8 extension. Put the extension, tap socket and easy out together and electrical tape it all together very tightly. Then if you break a plug push the porcelain down with the long punch and hammer (watch you dont go too far) then slide the easy out and extension into the broken plug and give it a few good taps to seat it in the broken sleeve and start backing the broken part out. It doesn't start getting hard until you start breaking plugs near the back of the engine.
