I did a test run with smartrent.co on myself.  

Buyer in the beginning did not want to be represented, buyer declined services from listing agency, LA accepted offer with buyers agent on the contract along with signed agency disclosure.

There are various services that provide sale data other than the MLS however many do not have as detailed information as the MLS. 

I bought a 100 year old house that probably had lead Paint throughout but I didn’t say it had lead Paint because I had never tested for it.

I tested a lender that funds 90% of construction and 95% of acquisition.

Finishing up my coursework and will be taking my test soon.

Make sure it explicitly explains the process for termination if you are unhappy with their services, but especially if they violate the terms of your agreement.3.

What i used to do to find services like that was to just find those people on google or google maps and give them a try (https://goo.gl/maps/JhUyEFKVXkH2) unless you can get a good recommendation.Typically, i would go over 2 or 3 different ones to see how well they communicate, how reliable are and how much they charge etc.

Or if you don't have the time to service those listings, then just get the leads and refer them to other agents for a share of their commission.

Because it is your credit on the line, you should designate the accountant/bookkeeper/servicer to collect rents and make payment to your mortgagee.
