The rest have a combined worth of about 1.5 million but aren’t owned free and clear yet.All Properties are collecting rent and generate about $16,500 (profit) a month in Cash flow after mortgages/expenses.

About 4 years ago we purchased a retail center for cash and after stabilizing the tenancies financed $650,000 at 4% fixed 20 years with this lender.  3 months ago this lender allowed us to wrap their note in a new first lien we provided to a buyer with a 10% interest rate - essentially granting us the right to collect the differential between 10% and 4% on the principal balance (currently $610,000).  

During this year, I've experienced inheriting a crooked property manager I let go on day 1 that tried collecting rents from tenants weeks after, an eviction (same person) and a successful lawsuit against a non performing seller that backed out the day of closing. 

If I hired a PM that would also take care of collections (among other things) would I still need a service like rent redi? 

They have 6 figure jobs and just want to collect rental income and move on from their job ASAP. 

You can collect a finders fee. 

However you've collected your fee since its easy to direct buyers how to buy the homes in markets where there's no barriers and hundreds are available at any given time, and the buyer feels like they accomplished something despite sitting on real estate that will never generate real gains. 

I recently evicted a tenant for non-payment and non-confirming the lease rules, and would like to file collections against her.

You need to make sure that how the money is collected is 100% collected prior to them putting a single door in the door.
