Is there a simple RF amp circuit that could boost the range to .5 mi or 1 mi?

You can use linear power amplifier modules (http://www.abacomdirect.com/Linear-RF-Power-Amplifier-PLA-05W-P93341C23620.aspx ) and for 1m you will need to use small yagi antennas, especially in the receiver module which has embedded PCB antenna ..
