This is important to me, because, due to the layout of my property (it is a HUGE open concept), I get a lot of people wanting to book an event space or have a party and they are located in the same city. 

@Elias Halvorson hit the nail on the head.  

Or can we assume an estimate if this is my only "job".Finally, if I had a cleaning company and they have 10 people who clean.

However crime is actually much less there than say Wilmington De and Reading has 30 k more people.

I did what people who were successful suggested I do, and it worked.

People have had success with all the options you mentioned.

If people put their hands on them, they get wiped down.The bottom line is both viruses and bacteria are quite fragile outside the body and they don't live long.One of my personal pet peeves was the "info" released early during the COVID-19 outbreak.

There are great people here which could guide me in the right direction and I appreciate any advice.

Don't listen to people who have never owned income producing RE.

They literally open till mid-night and full of people.
