Check out any reading material by Kevin Kehoe. I have been to his seminars, read his printed material and had him do 2 site visits to my company. Have also done the same with Vander Kooi and Jim Huston. Kehoe is the best. He is giving a seminar in Dallas this weekend for a very affordable price.
Also, join ALCA 'cause you get lots of info through that. Invaluable!
