Here's what I would do...
Present them with two quotes. One for the "bare essentials," like a minimal number of wireless mics, some new lights, light console, sound console, etc.
And, present them with a "top of the line" quote. 28 wireless mics, lots of lights, etc. This is usually how things like tis are done.
Idealy you would want to have someone come on-site from a local sound/lighting company and have them quote you. No offense, but this will be a bit more accurate, and better than you doing all of this yourself.
Anyway, good luck with getting your auditorium renovated. It didn't work out too well for us when we tried.
