Making over $60000 a year is really not all that hard. Here is the simple math. 3000 miles a week at a minimum of .40 cents a mile= 3000x.40= $1200 a week. $1200 x 50 weeks= $60000. Plus more if you get detention pay or drop off pay.
There are plenty of jobs that pay over .40 cents a mile. You just have to look for them. They are not going to come to you and drop in your lap. Its your job to search for them.
Of course if you really want to make some money you can go to work with some of the companies that pay .50 a mile. These are not that hard to find. They just don't advertise. Because they don't have to. Some of the are Yellow/Roadway, FedEx, Salis, UPS, ABF, New Penn USF Holland just to name a few.
