If you can say the City I'm sure people can highlight some local choices for experienced installers so you can get 2-3 bids. You know, like normal business approach to expensive implementations that are difficult to change.
If you haven't built yet it tells people where you are in the process and what can still be changed to meet your needs. Basic stuff like media/security closet for a rack of gear. Electrical plan for line and low voltage. Panelized or central lighting control or not. Drops for appliances, sensors, speakers, alarm system, security cameras, in floor heating, wall tablets, shower control etc. If you want automated lighting a lot of things can be different like a different approach to 3way or N-way lighting.
