I say go for it! This is what I've been planning on doing as my start-up niche (at least) because I have a lot of skills but I wouldn't say that I'm a total expert an any one (I am, however, very well-rounded
) and don't feel comfortable niching (is that even a word) until I find that one thing that just feels completely and totally "right". Currently, one of my clients is a brand new start-up business and I've been helping her set up her back office. It's been a learning experience for both of us and I'm loving it. It's very rewarding being able to help someone else.
