I took a wood certification class at the P*na event back in 2004 and was certified in wood restoration........before I had my equipment, before I had my trailer rig, before I had a lot of experience and before I cleaned hardly any wood at all, isn't that cool! hahahahaha
Since you are in Texas, give Doug or Danny a call, they can help you out and sell you some training to get you started out on the right foot with stuff that works in the real world and what equipment and chemicals you will need without selling you stuff you don't need.
Good luck.
