Business loan for start up O/O?

So one advantage I have in this is that, I have worked as a diesel mechanic for several years. I know my way around a truck. I can save thousands on maint
and repairs, being able to do alot of the work myself.
I am also planning on attending a course at a community college on freight brokering. I would like to be in position to be able to broker my own loads and save that "broker fee". The course cost is around 2k and runs for a semester and covers all the legal side, ports, negotiating rates, etc. Seems to cover all the ins and outs of brokering. I think this would be a valuable resource for generating business and keeping more money IN the business rather than giving part of it away.
#### the torpedoes indeed!!!!

 

I do have some of my own capitol to put in the mix, just not what I would deem as "enough" to start up completely. I haven't committed to the business loan but, have not ruled it out either. I am really just looking for suggestions or thoughts on the most effective way to start up.
I am wanting to purchase a truck, 53' dry van AND, flatbed trailer. I want to be able to be as diverse in the loads I can run as possible. I'm walking a thin line on wanting to make as much money as possible AND being able to spend time with my family. I think this combination would afford me the best opportunity to do both. I want to build a legacy for my family, not just a paycheck. Both of my boys are in college, business majors and I'd like to be able to hand the reins to a working business at some point and not just a truck and trailer.
