budget - hard to say without prints BUT
17 zones audio - depending on speaker selection about $40,000. I'd rack all gear.

surround sound setups depending on equipment and video selection. I'd rack all gear - allow $18k each but this isnt for actual theater rooms requiring engineering, sound attentuation devices, seating, calibration, etc. Need more info though

for the theater room, again, depending on hardware chosen and seating, I'd allow $60,000 for gear, calibration, mid level seating, engineering. Doesn't get actual wall treatments like columns, star ceilings, etc. Add another $40-50K for this.

Networking allow $2,500 for hardware and setup BUT this will not include any jacks

I'd budget, based on my above numbers, $200,000 to do your job.

Bet you had alot less in mind huh?

Be forewarned, you'll ALWAYS be able to find someone cheaper but won't always be happy with the end result.

When shopping for a contractor remember you get to choose 2 of the following: Price, quality, service. Want cheap then you pick either poor quality or poor service. Want hi quality and service - forget cheap.

Higher costs sting much less than poor quality.
