You can try the classifieds online for your state since most field service companies pay very little the only way to make money is to have multiple jobs in the same area.
From what I understand the pay is $25 on "drive by" inspection in which you will be required to take 10 or more pictures of the exterior. then you can get an additional $10 for occupied homes which still have a homeowner living there.
As in the case of unoccupied or abandoned homes can get you $40 for an interior and exterior inspection. You will be required to take 30 or more pictures, some require you to also change the locks.
One of the forums I read for inspectors says that Trinity Inspections are doing "disaster inspections" for several mortgage companies instead of draw inspections.
