Hello, from my perspective, i think that you ask yourself the wrong question.
The business opportunity and the job opportunity shouldn't be put at the same level to your eyes. The job should be seen only as a way to survive, in other term ask yourself what if you had your rent paid, your groceries paid and all your bills paid, would you go for the job and leave the business for an 'uncertain' after or would you jump directly to the business and try growing it ? All of this depends on if you can live without the job.
ps: The training provided by the job might be good but don't believe that you cannot train yourself by your own: set any small business to sell products even without profits and you may have the same training or even better one.
