know:
1. companies that provide and setup such networks if we
contract the whole job out. 
2. kind/type of equipment is required (difference,
approx prices, and range of wireless equipment) - best and price
conscious "good" choices  I also want to know the best. not model
numbers (but that would be nice), just the speific type of equipment -
servers, and wireless equipment.
3. what ready made hotsopt software for multiple locations
