start up... what do you think?

I am working on a start up and getting involved with a clothing store in their 5th month since launching. They really fill a niche market in my city and I want to get involved. However I face the following: 1. They have no clue how to run a business. Great visions but no idea on to put on paper then actually make it happen. 2. Staff is a lot of friends and many hands in the pot right now. 3. They have no marketing efforts but doing well. 4. It is a side project and does not have anyone’s full attention 5. I am not fully looking for a full time role but with some direction it can do very well. What do you think? Worth 10k??? Any and all advice is appreciated.
