Brian Tracy: You Are What You Think

I graduated this past spring with bachelors in psychology and i want to do something with it. I am in grad. school right now and i currently work at a mental/behavioral hospital. i would like to start a life coach business, but i’m not sure what is required. I want to know, do I have enough education background to legally start the business and what other legal stuff will I need to know about? I live in ohio and I have looked on the gov’s. site for establishing a new business, but it is less than helpful.
I want to specialize in high school sports and self-esteem building workshops.
Thanks
