for a variety of reasons i strongly suggest you get a book called the company we keep. its a book about worker owned bussiness. the worker owned model is very exciting and perfect ofr someone like youself who really doesnt know what your doing. functioning groups are generally more intelligent an idividual. the benifets of this model bounce well beyond money into community and sustainable local economy. i dont know where you live but most ashtanga studios are very specfic in thier technique and delivery. so dont worry about compettion. you could become the first worker owned studio ive come across in the twenty years ive practiced.

check that book out and get serious
dont doubt
dont be small
not with what is going on in trhe world today
thers no time
be big
just go for it

Work up a good business model, get advise from someone who know business, have goals and means in your mind before you begin. It takes commitment, big full commitment to make a studio profitable. Run the numbers. And plan to devote your life to it. You probably won't see profit for at least a couple years. Do you have the resources to get by for that time?

I run a small studio alone. I started with a cooperative model with about 4 other yoga teachers, but since I owned the property and I took the financial risk, it was really my gig. Things turned out better when I owned that fully. Partner or not will depend upon your business model, where the capital comes from, how you will divide responsibilities. Clarity is essential.

I have benefited from this advise from Lama Yeshe: you must have indestructible devotion, freedom from doubt, one-pointed concentration, and humility. And having lately read Cesar's Way (the dog whisperer) Calm Assertive Leadership is essential.
