You are not going to like what I am going to say, so maybe you should stop here if you don't want to read it.
1) Think --Why would anyone want to lend money to someone that has made poor decisions in the past? Unless they are going to rip you off with ultra high interest and expenses. Have you done anything to prove that you have started making good decisions?
2) Why not start making good decisions about finances to prove you are worth the trust? Here are some suggestions:
a) Get a second job so you can save the $5,000. Within a year you could put the money aside even if you only earn $6.00 per hour delivering pizzas.
b) Start a spending plan. Get in control of you money, so your money isn't in contol of you. By that I mean, you already have problems with living within your means, but earning more money doesn't solve the problem unless you can get in control of your money. I don't know how much you earn, but I've known people living on $20,000 per year that have zero debt and are doing fairly well. They are in control of their money. I have also known people earning $200,000 per year that are totally over their heads in bad debt, poor spending decisions and families that are broken.
So my suggestion is to take one year to save the money for truck driving school. In that year, get in control of your money and live within your means. There are a number of websites that can give you the training to do this.
Or call the United Way they have organizations that work with people in this area.
Don't call the people whose ads are on TV. They work to destroy your credit so they can get you special deals with your creditors. Well you will never get a loan under those conditions.
