What I would want to know is, since it's a team deal with the coach, would some of your team rides be prescribed workouts in a group, or would you be expected to do those on your own, in addition to the team rides? Especially since you mention a time restriction.
I'm working with a running coach for the first time now, and so far I'm pleased ... though I'm still six weeks from race day, and that will be the real tell. I hired him mostly because I knew I needed help setting goals. He's got me doing workouts that I could have sworn there was no way I could do them ...
I too interviewed a few coaches before making my choice. I found a very wide variation in pricing. I think you can pay a lot for a company's reputation, but flexibility and individual attention were more important to me, and I know my body well enough that I wouldn't be especially shy about backing off if I felt an injury coming on.
