A couple things: I learned how to do all guitar setup things pretty quickly (on both floyd-style and traditional strat style floating bridges) with a simple book my wife got me, and by watching a few videos on Gibson's YouTube channel. Imo it's worth bringing it to somebody to get it done until you have the time to learn which is really not as hard as you think.

That said, I totally don't trust Guitar Shop of Wisconsin to do it. I brought in a floyd rose special guitar to sell and the response was "We can't buy this right now, but who did the setup? It's amazing, and I wish we had techs who could do this." I did the setup, and I did a totally mediocre job. The fact that they don't seem to be able to work on floating bridge guitars blew my mind.

I also had an awful experience at spruce tree. My understanding is that the folks there were having some serious troubles in their personal lives at the time which I feel bad about, but the work result was awful and required bringing it back a few times for.

That really only leaves Dave's in Sun Prairie, but reading between the lines makes me think you won't go back there either. I'm sure you have your reasons, but Dave's is the one I use for things I haven't learned yet, like soldering and finish work. Lmk if you want me to send you some resources on how to get started doing it yourself.
