I'd be afraid to attempt doing it myself, even though I've seen tons of shows on how to do it. If you do it yourself, make sure you open the boxes and let the wood set in your house for a few days before placing it. I also know you're supposed to use the wood from all the different boxes because otherwise you might have patches of all the same colored wood instead it being mixed up. Make sense? I can't remember if the floating floor needs a vapor barrier or not. I, personally, would hire someone to do it. I think you'd save money in the long run.
