Hello djbwoo,
Running any business be disabled or not takes many things... location location location, knowledge of the business, money and intense intererest and time in it.
Most will agree any business venture takes the first five years to either make it or break it... with little profits to banter with, the expenses are large and many ...and the restocking investment with increased overhead be at home or other are rising daily..
Not to discourage anyone that is considering it tho to acknowledge that it is a committment like never before to make it successful with lots of time and patience.
Good luck should you consider such. ohyojj ~
