Business Radio on a Very Tight Budget?

What is the longest range 2-Way radio system I can set up for less than $200?

I’m thinking about buying a pair of handheld two way radios for my small consulting business. I would like as long of range as possible since I know you get less distance due to building obstructions and weather conditions.

Both radios should have a recharging base they plug into.

I’m looking into this as an alternative to wireless phones since I would only be speaking with one other person 95% of the time (my dispatch).

Using these type of radios would cut down on the need for a larger calling plan with phones since most of my clients are within the same 5-10 mile range. I don’t need private/encrypted channels but the FRS channels around here are too busy with other users.

I’ve seen GMRS radios advertised as being capable of working up to 18 miles. But I would like to  find a longer range than that if possible.

I am quite willing to apply for a FCC license if needed.
