Quite.
I'd also expect a set up to be part of having a neck shim, especially at that price. You can't shim a neck and then not set it up, well you can if you just don't care, but I wouldn't want anyone like that working on my basses anyway.
It almost sounds like he's priced the job out of the water as he doesn't want to do it.
If you (the OP) really don't feel able to do the job then that's fair enough, but it really is a string of simple, small jobs, rather than a big, daunting task. Any number of folks on here will be more than happy to walk you through it oe step at a time.
Best of luck whatever route you choose. 🙂👍
