I've talked to the coordinator for the Salt Lake Safe Kids before and she's been fine with people out here going to their checks, but I shot off an email to her to make sure. I intend to work as many of those checks as I can.
We do have a local mom's online group of which I am a member. The ladies there do know to ask my advice for choosing car seats, but so far they've only talked about having me help them with installation issues.
I know I'm cocky and inexperienced, but I actually have had some experience installing many different kinds of car seats. I've gone through about 30 different seats for my own kids in various vehicles, using latch, seatbelt, and locking clips. I've used alr, elr with sew latch plates, locking latchplates, and switchable retractors. I've bought car seats, played with them, then sold them. I've tried the various methods of installing those seats as well. Then, when people buy the car seats from me, I often show them how to install the seat in their vehicle. Last week in class, I purposefully chose to install car seats I hadn't installed before and installed them in all the methods available in various other vehicles just so I could learn. I now feel pretty confident in my ability to read manuals. They really do help a lot
There are now two CPSTs in my county. (Which is huge.) The other CPST works two days a week, 8 hours a day, is hard to reach, and tends to not return calls. I feel that having my skills available to the community can make children safer than they currently are. At this time, I am willing to take the risk that I might not know everything. I am very comfortable telling someone "I don't know. I will search for the answer."
ETA: the Salt Lake coordinator responded affirmatively to advertising their events out here
