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

I’ve read Keller Williams is great for their training programs but you may not care about that if your mostly looking to act as an agent for your own deals.

These are professionals with additional training and a stricter code of ethics.

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.

My main plan is to sign on with Keller Williams because of their in depth training.

Thanks @Omar Khan,  those services would be avaliable from a local commercial real estate broker correct?  

Does someone have a script that could be provided for wholesaling services to a company like Patlive?

In saying that, depending on your level if knowledge, option 1 is probably a better one. because $3000 is not enough of a buffer to service the property if you need to repair things.
