Gary,
The propane buffer is only if you will be doing VCT tile. They do have a lot of carpet, and upholstery which is mainly what we would be doing for them. They do not pay a lot, but it is a way to bring in some money in slow times. Any company like this will have a lot of hoops you need to jump through, but once you are in then it is easy for them to send you a lot of work because you have already jumped through all the hoops. I do not recommend that any of you buy a propane buffer and do the VCT tile work. We want you to do the carpet and upholstery, which is what you do best.
