Who to call for a custom built loft?

My wife and I recently moved in to an apartment and we are interested in getting a loft built for our bedroom. Our bedroom measures 76″ wide, 102 3/4″ long and 123 1/2″ tall.  We are specifically interested in building a spanning bed to fit a queen bed.  I emailed Sticks For Stones this past month and they sent me back a price quote.  When I emailed them back to say I’d like to have it built the email keeps bouncing back and when I call there is never an answer or voicemail returned. Any recommendations out there?
