i am looking to install a rollup steel garage door at the entrance to my driveway from the alley (city row house). there isn't an actual garage, just the driveway but there are fences on both sides of the driveway. i was gonna use a 14ft wide rollup door, as is seen in some commercial applications (e.g. apt building parking garages etc.) but want it to be rollup because i want to have only 2 posts (cheap garage doors that lift to the horizontal position have rails that are suspended on the ceiling and i don't have that).
basically i am looking for a recommendation for a company to order this custom made door from. and a rough guesstimate how much it will run me $$-wise.
