SPARK PLUGS on 2003 Chevrolet Venture

Is there a way that I can change out my rear spark plugs without having to go to a mech? I did the front 3 with no problem, but the back 3 ? I cant even see where the wires go back there?
If this is something that I should have someone else do? how much should I be expecting to pay?

If you can get under the van it's easier . Cottman can help for 89 dollars if you supply the parts
You will want to access those rear spark plugs from under the vehicle, it will make it easier.
The rear spark plug wires tend to be stuck on the spark plugs, because of heat. So be careful you do not pull the wires apart.
