I think getting a coach is a superb idea...and I'm not just saying that become I'm a life coach!
I too have a life coach and I chose one who was more business orientated. I don't really need any help when it comes to my PersDev but I needed help with expanding my business and getting to a point where I can quit my job and be self employed.
No matter who you are, anyone can benefit and will benefit from getting a coach but you do need one that you have a great rapport with and someone who you can respond to easily.
Whatever you choose, good luck!
