One-Time Deep Cleaning Service?

Hello! We’ve moved houses from one part of town to another and we’re getting our old house ready for sale. We’ve got it emptied out, I’m doing repairs, but we are considering hiring a cleaner to put the final details on the house ahead of sale so we can get that task off our plate. We need a service that can vacuum, mop, scrub baseboards and cabinets, bathrooms, etc. basically deep clean an empty house so it looks clean to prospective buyers.

Can anyone recommend a provider that does one-time cleanings like this? I am finding a lot of cleaners but it seems that most of them are contracted/want to have a recurring service rather than one-and-done.

TIA!
