How much to charge an investor for finding great rental properties due to my experience having already done that and getting great rent?

Hi Everyone.

I'm a Realtor and an Investor and I'm looking to work with investors who want to buy and hold.  My experience with them (as I currently have purchased such properties and they are great rentals) provides for a shortcut for a newbie investor.   How much do others like me charge investor buyers to find such properties? Does it include the commission that the seller will pay (3% usually)? A quick response would be great because I'm in that situation now.

Thank you
