I have worked with RPGPundit on my project and I want to say that I found him highly professional, knowledgeable, thoughtful, and his pricing has been perfectly reasonable. If you are looking for consulting help with your RPG Rules Book, I recommend that you inquire with him about it. He is an excellent person to work with - so long as you are willing to hear and act upon a perfectly honest assessment of your work. I could not recommend him more highly.
