My first job was a caddy. I caddied at Butler National. In general an honor caddy is somebody with experience, but don't expect a tour caddy.
A good caddy should keep pace with you, a good caddy will keep your clubs clean, replace your ball marks, rake the traps, fix your ball mark on teh green, help you find lost balls, clean your ball on the green, etc.
In general what ever the base cost of the caddy is, you would make the tip at least that.
