Most of my properties have accordian style sliders so pretty easy but one house has those heavy panels that one took a good 3 hours as the tenant apparently used some of the panels and attached them to wood fence gates to stop his dog from passing below, and a few other panels for other purposes. 

That would save you on every cost but the panels themselves.

My experience with a "professional electrical inspection" typically involve looking at the meter weatherhead "visually", taking down the electrical panel cover and look inside and see if there is any cause for concerns (double tapping, mismatched wire gauge & breakers...), testing and resetting of one or two kitchen GFCI receptacles, plugging in a few receptacles with their $10 tester and making sure the "CORRECT"s are lit up. 

The downstairs would be up to code for everything but a separate swicth panel, which would need to be done.

I hire one for plantation shutters installation, they brought a crew of 3 staff to hang 4 panels.  

I don't want to upgrade breaker panels and they don't want design network infrastructure, but in Maryland, you must have a Master or Limited Electrical license to pull a permit for low voltage installations. 

The attic is off limits, so we close that off with a wall panel which can be removed for maintenance access only.

FRP panels for walls in wet rooms, VCT for wet room floors, 1x4 screwed horizontally to studs & towel bar mounted to that, *no* soap dishes in showers, high gloss white paint for trim, *no* carpet, 

I know this may sound crazy but I never even look on the MLS, you'll find me in peoples living rooms, dining rooms, and kitchens asking them to give me an estimate of what it may cost to remove that paneling and possibly texture and paint for the open market.

I may install three panels of vinyl fence in tan color, this will help keep their rat dogs out of my yard too.
