I am not sure if that was an error or they are trying to rip you off.

Did you buy the paint for the painter who is doing side work from his regular gig... probably your employee now as far as the state is concerned. 

In the case of wholesalers if the profit was disclosed to the seller like a commission is with an agent there would be a lot less unsuspecting sellers getting ripped off.

Ex: If a tenant calls up to complain that their drain is broken or running slow, or that a light fixture needs replacement, or to spray the Apt with insecticide, or to fix a broken door-lock or window frame, or anything of the like such as the fast repairing, touching up, painting & cleaning needed during a turnover between Tenancies...

The home was mostly turnkey, but we painted the interior and exterior (we always wanted a black home) and provided all new light fixtures and furniture.

I have a painting business and my partner has a construction business in nyc and we've already been doing jobs in CT. as for time I have loads of time on my hands and I am pretty handy my self.

meaning painting the exterior LOL.

Share leases, co-op on painting, etc.

Examples included missing paint and rotting siding.

If you go the wood framing route you will have to rip the joists that sit on the concrete because garage floors are built with a slope (for water runoff).
