Here is the place one of my neighbor's coworker had found and used with success over a year ago when we were all looking at doing this stuff at home. However, you must have some room.....or at least it helps to have room....
There was a show on years ago, called "Lost in Space" that featured a robot that was always saying, "Danger." After reading this OP's link, that's all I can think of... Dang, the stuff that the author of that link is using, while effective, can REALLY mess you up. To me, it's not worth the risk...
The only thing that you have to worry about is to use the right precautions like gloves and safety goggles and take verry good care with the chemicals.
