There is a company out there that has a good product. I got their regrouting training video and I learned a lot! The recaulking video was great and it was only like $20 bucks or so. I learned more then I knew I could about recaulking. I can't wait until their tile repair video is done. They are the first place I have seen to offer this kind of money making information without having to join a franchise! Just get the videos and learn. They gave me a good package deal on the first two videos I got. From what I understand they cut home owners a huge deal since they are not using it to start a business. Anyway, just thought I would put my two cents in :) The web site is at www.save-now.com or here. Let me give you the exact link... http://save-now.com/grout/GROUT-SERVICES/Training%20Video/LEARNING-MAIN/index.htm
