There are a number of different businesses that use delivery drivers, but only a few that hire independent delivery drivers with their own cars who charge per job, rather then by the hour. Companies that hire independent delivery drivers include just about any business that needs to make deliveries, but needs an independent driver for special jobs.
People who own their own moving trucks or vans can be contracted to move furniture from apartments or homes for a rate that may be cheaper then someone renting their own trucks or vans or hiring an established moving company to have their own drivers on payroll move their items. This depends on how much the independent movers will charge to use their vehicle and move the items from pone place to the other. Sometimes moving companies will hire independent movers themselves when they have all their salary drivers on other jobs or would prefer to use an independent contractor to move the client's items. Independent movers should have insurance on not only their cars but the the items they move, though the person who contracts them should purchase this.
Couriers are a type of independent delivery job that delivers packages and letters that are incredibly important. These jobs are often available for independent drivers who have their own cars and are either hired by a larger delivery company under delivery contracts or make contacts with companies to make deliveries for them when necessary, yet still maintain independence to take delivery work with other companies. As couriers are delivering only a few packages or letters at a time, they can use small compact cars that are their every day forms of transportation. Couriers can also charge companies for gas and mileage.
Runners are often hired by companies to be the delivery person for a particular company but still have the ability to be an independent delivery contractor. They are often hired by media companies or legal firms in large cities who often need to send things from one location to another, back and forth over the course of one day. By putting these independent delivery drivers on payroll as runners, these larger companies don't have to spend as much money on a courier service and can deliver as many letters or items as they want during the business day. These drivers often pay for their own cars and insurance but are given a stipend for gas and mileage on their cars.
