Lots of training programs on the web for this kind of work - which is sometimes indicative of a business that sounds good but is actually very difficult (like Medical Billing or something). I gather you work your ass off trying to find a shipper with whom you can build a relationship... and then, nowadays, there are 7 trucks for every load. So the truckers can squeeze whatever profit you're trying to make. Frequently, the truck blows you off because it found a better paying load, then your shipper customer loses trust in your word.
High fuel costs also squeeze the margins.
I thought the above link was kind of strange, since a reader might expect to be alerted to a scam. But the link is actually a training program whose owner wants to let you know that his program has consistently passed the Scam Review process (if such a thing really exists). But there are a ton of other training links.
