I have done a few of these for an outfit called Advanced Field Services. Pic to verify address, pic of front of structure, pic of rear, note any hazards (include pic of hazard) or conditional problems. Thats it, takes about 15 minutes from start to finish at the most. Upload the pics to their website + simple report which takes maybe five minutes. You can hold a report request for up to two weeks, so I wait and group them together by general vicinity. Did 4 of these last week in less than an hour, including driving time, and I was already in the area doing one of my jobs so it wasn't to bad.
