There are two types of Tasks within Hyer. There are Public Tasks, where the Task is view-able to all Taskers within your area and any Tasker with the proper qualifications will be able to apply to the Task. You also have the option to Choose Taskers. These allow you to choose the candidates that you think would be best for the Task.
How do you Choose Taskers?
Making a Task private is done at the last step of Task creation. When you get to the "Post This Task" page, you select "Choose Taskers". This will allow you to choose from a list of suitable Taskers in your area that have the chosen Task category listed on their profiles. You can sort the candidates as you see fit, and even mark candidates as "Preferred Taskers". Once you have sent a Tasker an offer, they can either accept or decline. If the Tasker accepts, they are automatically scheduled; if the Tasker declines, you will receive a notification and you can choose a different Tasker.
