Hello, as a former Shack geek in my college days, I was the deferred to as the "expert" on just about everything most of the time, unfortunately. On one hand it was because I probably did know the answer, on the other, the evening shift guys I worked with were "gravy" guys....they only wanted the easy sales, and were too lazy to work for it. Guess thats how I ended up a keyholder too! 1. I would look for a Kenwood or Motorola dealer if you are serious about building a small business system. There has to be someone near you somewhere. 2. You can look here: http://home.provide.net/~prsg/ 3. GMRS is for personal use, not business use. The exception is "family" businesses, such as farms, etc where all radios are operated by family members. You could technically license all individuals for GMRS and then all be legal to talk to each other...but that is impractical to do, and maintain with employees. You need to use MURS (2 watt VHF) for business....or license it with a coordinated business frequency. You can use a repeater then as well (MURS you cannot). Enjoy GMRS for personal recreational, etc use...but it's not meant for business, nor is it legal for that. I do know some businesses that run on FRS just to use CHEAP radios....but a real business deserves better than FRS. Look into real radios in Part 90 service. http://www.ancom.org/ - Motorola https://www.google.com/maps/place/Co-Meg+Sales/@43.85278,-92.488236,17z/data=!3m1!4b1!4m2!3m1!1s0x0:0x166aeba8d4da6cd0 - Kenwood
