Well if its in possession of people who don't agree/dont want to work on it I would get it out of there ASAP. Personal problems between techs/builders like that can ruin projects iv seen it personally. I don't know of anyone particularly in Denver, but I know of specialty z. Can't speak on build quality but they have always been great with sales/service for me. If I were you I would want it done by specialty z if there is no z specialist in the Denver area, but if there is, I would want my investment as close as possible to keep track. Good luck!
