Potential for high earning in short time. Management was usually easy to deal with. Flexible hours. With the right time Management i could work 1 week on 1 week off and still bring home like 3k for 2 week paycheck.
Cons
Use of own vehicle and supplies. Which can have a costly start if not already available. Need a car, camera (camera phone), computer and a phone w/ GPS and probably unlimited data. As well as a camera pole (think giant selfie stick)
