Hey all Truckers, I am trying to get my husband into his own truck but I need information I'm hoping ya'll can help with.

Here's what I need to know. If he gets his own truck he will have to make enough money to pay our current bills plus a truck note and insurance and operating cost. So what would be his best bet? Contracting out or job board? And could someone please through me some numbers in there. I would like to have my ducks in a row before I tell him to quit his current job and come home. Thanks in advance
