Did a quick search, Google and Biggerpockets and nobody has reviewed them.  Maybe they are too new to the game.  They look like a one-stop-shop for all of your farming needs, starting at $650/month.  Any experience using them would be greatly appreciated!  

Btw, they are getting a good push from Tom Ferry.
