It's a 9' ceiling and all the ceiling joists are spaced exactly 24". I ran 2x4's across them at intervals and screwed them down to make certain they were 24" on center.I have access to a lift so maybe I will end up doing it myself. I've done this much and more. Just know that it's going to take me longer than having several people come in and do it.I have a lot of material in the way as well as many tools and cabinets. I'll have to move all of that out of the way. I've been doing that since I started this project.It was just a thought that my wife brought up.Thank you.
