Baofeng + CHIRP + FRS/GMRS Freqs = 5 Watts of Awesome
Just make sure you actually limit the FRS channels to .5 Watts to stay legal.
If staying within the letter of the law is not paramount to you, this is the best (& cheapest) way to go.
(even broadcasting at under 0.5W there are a bunch of other rules that you would not be in strict compliance with)
