Lots of options here only limited by how much you want to spend. We have a UHF repeater on a tower and use handhelds. We've invested about $5000 in this. It would have been much more, but I have the tools and techincal know how to do the work myself. We get about a ten mile radius with our handhelds, mobiles quite a bit more.
There are three license free services that will work for you if you are only trying to cover a small area.
FRS - Family Radio Service. This is licensed by rule so no individual license is required. These are low power (0.5 watts) handheld radios that operate in the GMRS portion of the UHF band (462 - 467 MHz). They advertise as have awesome range. In reality, if you can see the other person, you can talk to them. If you can't see them, you may or may not be able to talk to them. UHF does great in urban areas, but not so great in the woods because the signal is absorbed by leaves and esp. pine needles.
MURS - Multi Use Radio Service. This is licensed by rule so no individual license is required. This is a VHF radio service that has four channels. Two watts is the maximum power level required. You can have a base station, but there are some limits to antenna height and gain.
CB - Citizen Band. This is licensed by rule so no individual license is required. This is the low band (27 Mhz) AM radio service that has been around for ever. The legal limit is 4 watts. Because it is a low frequency, it is hard to have an efficent antenna system because the antennas are quite large. A quarter wave antenna for CB is 102". I know there are lots of base loaded coil antennas that are smaller, but those are a compromise because there is less capture area for the antenna to receive with.
Now for the more costly, licensed services...
GMRS - General Mobile Radio Service. Basically a higher powered version of FRS. You can have 4 watt handhelds, 50 watt mobiles and base stations, and you can have repeaters with no limit on antenna height or gain. A license is required. It's $75 for 5 years and anyone in your immediate family can operate under your license.
If you are trying to cover a larger area, you may want to contact one of your local radio shops and see if anyone has a community repeater or trunked system you can subscribe to. If you are only wanting to talk a couple of miles, then GMRS or MURS will work fine. If you are only needing to talk back and forth around the field, then FRS will work.
NEXTEL, or since you are in Georgia, Southernlinc are a couple of wide area two-way radio systems that also have the ability to make phone calls. NEXTEL is sold like cellular, but it is actually an ESMR - Enhanced Specialized Mobile Radio service that has trunked two-way radio with cellular styled interconnect(phone calls). Southernlinc is another ESMR provider. These two will give you wide area coverage, along with a large monthly bill.
Hope this helps...
