Ask HN: Growing a Company?

I'm not sure if this falls into a core competency area for HN, but not sure if there is a better place to ask. One of my friends has a business with about $12 million gross revenues. He wants to grow it to $60 million revenues within the next several years, and knows that things need to change, but not sure exactly what to do and the order to do them. I assume there are consultants and coaches to help, but how do you go about finding them? And what other resources are there?
