Hi Jeff,
Welcome to the world of helicopter flying. I haven't used PLH, but I know two people who have; both have PPLs and are now working towards CPLs. One was very impressed with them. The other said they were good at the beginning when she knew nothing about the rotary flying world, but she now felt she had enough contacts to get the information she needed without them. I haven't heard anything bad about them - always a good sign.
It might be worth posting your question on Rotorheads to see if you get any more info.
