I would start with LinkedIn. They have a section called 'ProFinder' which has a huge number of listings for career coaches of all sorts.
I have been working with several people found here this year (for very different reasons than yours), and I have found some great help here.
That being said, as with everything on the Internet, you need to do some filtering. There is a fair amount of noise in this system, LinkedIn does a pretty good job of filtering out the scams and crooks, but you still need to make sure you find the person who is right for you.
Most of these people offer free 30 minute consultations. Get on Skype with them and ask them questions. Be honest with yourself about what you need and what they are saying. But also push back a little and challenge them. These people are selling a service and they will try to persuade you, but their talents and areas of expertise differ greatly.
I found one coach who was great at helping me rewrite my resume and LI profile, but really awful at helping me with active communications.
I suspect you will find many coaches who will tell you to quit and tell you how to find a new job (for a fee). But if you search, I think you will find someone who can help.
Good luck.
