For instance at one of my properties, I have a duplex, and I have a handle on rent collection and other services but I need most of my help with maintenance calls. 

If you intend to do a 1031 ask your title agent for a qualified 1031 company to handle it and they will walk you through it.

You may want something that can handle 90% of what you do rather than just 20%.

My goal was to understand everything about real estate so I could handle big problems if they arose.My next plan of attack was to research a few mortgage lenders to see what I could be approved for in a multi-family property.

I however am looking to hire a full time W2 employee to handle day to day operations and coordinate between these service providers and run things generally under my supervision.Need help with actually structuring the job description, company standard procedures, and most importantly how to find and vet this person.

Who will handle the evictions, the troubled tenants that call at 2am with no heat, stopped toilets etc.Add on that probably no one likes their PM. 

I'd only get involved with flipping if you can handle the risk and you have a team who is able to get it done in a timely fashion.

What are some recommendations for PMs in the area that can handle a single property up to 50 units?

When you don’t have that experience, you will be best served by having an agent handle the contract and paperwork and be able to explain everything throughout the process.

I also know a Vacasa representative in the area that has full service options and a huge staff that can handle as many you throw at them, so it might be a good scale option.
