Choose the shop you are most comfortable with. There are two LBSes in my town. I have bought from both in the past. I now only give my business to one. FWIW I have purchased over a dozen bikes in the past 30 years, and probably sent 50+ people to the one shop I support. I took a vintage frame in the other day to have the bottom bracket threads cleaned up, I was fully prepared to pay for it. They told me no charge. This is part of why you want to build a relationship with your shop. On the flip side of the coin, they have called me a couple of times asking where to get some obscure IGH parts or if I know how to deal with a particular issue.
FWIW I do 99% of my own work because I enjoy doing it. I only take stuff to the LBS when I need it in a hurry or it is beyond what my tools will handle.
