I believe that inspectors need to have a licence now.

After getting the licence, can I start up my own firm, or do I have to work for another real estate company for 2 years before opening up my own? 

Its their labor,   truck costs,  disposal costs,   licences, certifications, and all the taxes and stuff they have to pay.Also be careful that the full wall demo (last picture,  with furnace in it)  isn't a load bearing wall.if you are inclined and able,  stripping a kitchen down to bare room  isn't that hard  (kinda fun too to smash cabinets with sledgehammer)  but make sure you are able to haul the materials to the dump,  which may mean renting/borrowing a trailer or pickup if you don't have such equipment.   

As I often tell people, "Perfection" is a fictitious town in Nevada from the "Tremors" movies - stop looking for it.
