Mike,
Great goal to go for in the long run.
Get your certs first so you can see how you feel about helping others and running the show at the same time.
My personal thought, if I had the required funding, business plan, materials, and resources, I would still prefer to work for someone else. Owning a business is great but when the responsibility of running a business takes away from the passion of what you like to do (help people), there will be problems.
Aside from what everyone else has said above, keep in mind "you are the ultimate "chief cook and bottle washer"
Not to burst your bubble, JMHO..
