8 zone hybrid heat pump installation cost

[Chris Chris]

Looking to freshly install 8 zone hybrid heat pump; (The heat would come from a heat pump until it's 35 degrees outside and then the system would fire up a natural gas furnace inside the house.)

Not exactly looking for high end but mid-range.

Looking for ball park how much would it cost to install hybrid system with duct (for 2400 sq.ft house of split foyer style).

** I understand the variables involved in this, just looking here if any one already installed it and have some idea about it with pricing **

thanks
