Have You Ever Hired a Life Coach?

Curious if anyone has every paid someone for "support" for the things they go through with business, life etc?

I was approached recently by a guy at my church. I've talked to him before, good guy and I liked his perspective. He basically said he helps guys (a lot of business owners) find more balance and purpose yada yada yada. 

I've had a life coach before. My experience was that he helped me through some personal stuff, my business was really early on so I was easy to coach in that regard (lots of things to suggest) but the relationship started to become more of a chore and a complaining session than experiencing breakthrough. We ended it then we picked it up again when he put together a group of guys that were supposed to be similar but ultimately I didn't find a lot of value in that. Still talk to the guy but this new gentleman approaching me, made me kind of relive that. 

Have you ever hired someone for this? What would you expect out of them? What would you tell someone that might hire a life coach?
