I will be certified to teach yoga in April and am working on my business plan now. My idea is to have a roving yoga business with an online presence. I provide the mats (when necessary,) and can come to your school, company or club. I will also teach classes at local studios and private clients at my house. I will have insurance and be CPR certified. Do I need to form an LLC, or can I do this as a sole proprietor? What are the advantages of both?Thanks to both Alan and Douglas for the responses! What a wonderful forum this is.
