Go the route of Power Yoga, Anasura Yoga, and YogaFit to name a few and create your own unique yoga style.

Advantages to developing and teaching your own yoga style:

easy to expand / franchise,
can bring in partners,
transcends geography,
if you’re successful, you gain added credibility which may help with book and DVD deals, other product deals, and being feature faculty at retreats, seminars, conferences, etc.
create demand (niche style) which may fetch higher prices,
opportunity to create a high-profile teacher training school,
students don’t mind if other qualified teachers teach them (don’t necessarily expect you to teach all the classes),
low demand for a unique name on the search engines so with good branding results, you can achieve excellent search engine ranking.

Disadvantages to developing and teaching your own yoga style:

may cut yourself off from teaching other types of popular styles (it’s not inconceivable to teach multiple styles including a style you create),
requires lots of branding effort – it’s a huge undertaking,
may invest lots of time and money into developing the style and marketing which may not work,
low or no initial demand for searches on the internet. Until demand is established (through branding), you may not have lots of search demand (unless you build a great content Web site),
