Saltwater pool converter

I need a quote for equipment need to convert our condo pool from a chlorine based system to a saltwater based system. The pool is T shaped and has two separate hot tubs. The total volume of the system is 107,110 gallons. Please calculate the equipment size and cost for a converter that would last about 5years. 
The association will do the installation. 
my very best
