Great question @nomad! Just go to the services section of your account, set up your preferences and select travel preferences. You'll need to do this for each service to get the jobs that you want. This article has more info, be sure to check it out!
What about if the choice of travel preferences that tt give me is to big for my coverage area. I would love to choose the areas were I promote my business. Unfortunately I can't, because when I promote I am loosing money more than making. If the travel preferences is to big. Then I have to decline jobs, because is too far away. You guys should use zipcodes instead of whole county's.
