Cleaner recommendations for deep clean??

My partner and I recently bought a duplex to live in/rent our renters just moved out. My initial plan was to clean it myself as I have a background in professional cleaning and felt quite confident. However, upon seeing the apartment and how bad it is coupled with the fact that I am almost 7 months pregnant...I am now considering hiring a cleaner to save myself from the fumes and back ache. I just want them to do a good job so I don't have to go back over their work. I'm kind of a clean freak, so I really want it to be spotless.

Any recommendations for cleaners that can reliably deliver this? Maybe specialize in it?
