thinking about a tool truck franchise

i would love to do auto estimating but the companies want some young college grad that knows zip about cars that way they can train them the way they want to. I did apply for a progressive job and was called for interview, however job was given to a buddy of the other estimator. Seems like it is a who you know not what you know. The job i am at know i have been with same boss for about 15 years, however hes 63 and i dont know how much longer he will be here.i have no benefits at this job.Wish i could get a job as estimator but been trying for years the positions just are not there.
