I have to agree with the other posters. I am new to expediting, I started in April of this year, I am not new to driving straight trucks. Expediting is a whole other beast. My company is not a true expedite only company, but I am still struggling, I'm going to make it, but it hasn't been easy.
What happens when your truck breaks down? If you are broke and have to borrow 10K from the grand parents where are you going to get 8K to repair your truck? If you have the 10K in a savings account for emergencies, then that is a different matter. Once you buy the truck and use that money, you have no emergency fund.
I lease my truck, and get a lease replacement truck when mine is down, reciently it has broken down and been in the shop for over a month , the first four times they spent over 6k to repair it, the fifth time they spend who know how much to tear the engine down to replace # 2 cylinder(estimate at least 4k) Do you have 10k to fix your truck? I sure don't. Check out my thread "My Hino Nighmare" If I wasn't leasing I'd be without a truck and a paycheck for over a month, Can you afford to do that?
Take everyone's advice drive for a fleet owner, get some money in savings, the more the better, and then think about becoming an owner operator. Maybe the economy will recover by then and you will make it, sorry to say it sounds to me, like you are setting yourself up for failure, and not even with your own money. Just my opinion!!!!
