By that I mean the basic set up you see at competitions: -spot lighting (couldn't find a picture that fit, but basically think of the pitch blackness you saw at All England 2011) -umpire -lines people -service judge (this is huge I think) -digital scoreboard -etc. Would all this stuff create a sense of occasion big enough for your ultra serious badminton player? How much of a premium would you pay? I think this could be huge for cash games.
Players who are in it for an amazing experience, as a birthday gift certificate kind of event, will want additional attractions, for example famous players to play against (or with). The market for this is probably proportional to the number of Badminton fans, i.e. players who watch official games somewhat regularly. My impression is that a huge percentage of players - even those playing in a league - only play and don't watch. For these people, you're offering a nice but really really expensive court. Some players may also want to prepare themselves for their first official tournament, but they can simply enter a lower-level tournament to get a feel for the experience.
I think most games played at a regular badminton hall are entirely forgettable. We play to work up a sweat, and as a pass time. I think having a facility like this makes games more meaningful, and secures bragging rights by basically having all the features a regular competition would. I don't see this as a 'fan experience' type place. By 'ultimate' i simply meant as close to official competition as possible.
It all depends on the cost... If only 10% more than the average usual at various badminton specific gyms with pvc mats, then there'll be demand. But if 50% more, then it'll be tough sell...
You basiclly need to hire 10 people for an hour. That will be 10 times the price of a normal court. Seems like a good business plan to burn some money... As a side note: Playing with a ref ain't that special. It's cheering spectators that make matches special.
