Ditto all of the above comments.
Since the downturn in new carpet sales, the number of Carpet Inspections have also gone down.
You will learn plenty and it will be a stepping stone to many other kinds of Inspections -
Resilient, Tile, Concrete and Wood.
There is little room for mistakes or sloppiness ( especially in Court ) so if you are going to do it, be sure to either do it right or not at all.
The best paying customers are lawyers but don't go there until you really know what you are doing.
One other consideration is that once you get old and decrepit and or retired, Inspection work is something that you can do long into your old age.
