Employees are paid wages.  On PetCloud you are not an employee. You are an independent subcontractor. As your own boss, you set the prices displayed for the services you offer on your listing.

Pet Sitters and Dog Walkers should value themselves and their time, effort, and money it takes to drive to someone's home, or to walk a dog.  For reference though, the Australian minimum hourly wage is currently $21.38 per hour.  Then think about additional expenses.
