All the Cozy builders in Houston seem to be over by Ellington field for the most part (must be something in the water there). I did see one parked at the Sugar Land airport last week, but I'm not sure if its based there or was just passing through. If I see it again I'll be sure the write down the r number.
I would recommend you sign up for the Cozy Mailing List, if you have not done so already. I almost have the wife convinced, at which point I will order the plans myself. It would be nice to have somewhere nearby with which to compare work.
