In my experience, it's really hard to get someone good who can do a plumbing job, or electrical job, then patch the drywall & match the texture well. You need to search for a "Handyman" service for this & often you're getting a jack of all trades, expert at none. If they really are amazing, they're booked solid & no one will ever recommend them to you as they're already hard to get an appointment with.
For a lot of specialists like drywall, the really good people seem to never want to deal with small jobs. They get paid better & it's easier to do large jobs.
