Looks like you are from OR so I'd say post up on the local PNW subforum and see if any locals are willing to spend an hour or two on the weekend with you to change the oil.

Find a specialty shop that works on mounting/balancing tires in your area. Might cost a little bit more but it might take the edge of your worries.

Now if you are worried about scratches, take your cellphone (that hopefully records in decent quality) and do an entire walk around of the car. Note verbally any pre-existing "defects" such as scratches, chips, dents, etc.

I'm not opposed to the dealership completely since I'll be taking the car in for a fuel gauge issue next week.. and they could possibly taking apart the dash and other parts. But oil change is super simple, and I admit I am extremely lazy.
