The answer to your question is, that you must think like a coach yourself. Why would you coach somebody? The first step to coaching others is to understand why they might not already be performing at the level that you would like. This intention is necessary for you to coach anyone successfully, even if the intention is hidden beneath a poor attitude. The common reasons are:
1. They lack the required capabilities.
2. The job is not challenging enough.
3. They feel they are not appreciated.
4. They feel they have been overlooked in some way.
5. They have personal problems.
Now, can you relate yourself with the problem that is barrier to the business? If yes, that is the area you must coach yourself and you can find a good coach either in books or a credible website and talk to them for resolution of the same.
