Stop in to any place that does custom millwork... they'd be more
helpful than you may think.
Home Depot made me some 28" wide 6-panel doors for $50 a piece.

For an opening like htat, you may want to consider double-swinging (or
whatever the proper term is) hinges. Lee Valley has these. If it's
a bedroom (why would you want glass then?) then normal $2 hinges out of
the box on the shelf at home depot will do you. (don't buy the ones
they have in the package on display...they cost more than twice as much
than the basic stanley hinges which look exactly the same)
