For number 7: i would also say instead of buying yourself a truck buy one and put it with an employee first so meanwhile whilst your driving for other companies you have also got a driver driving for your company.
At least you got 2 lots of money coming in then buy yourself a truck after awhile or buy a 2nd truck for another employee then save up and eventually buy a truck for yourself or upgrade garage and then keep buying trucks until you fill your garage with drivers and trucks.
