Simple_Gesture in the Gallery

What does it cost to have a full cockpit enclosure made like the one on Simple_Gesture's boat?
The rig I am considering has the stand up type bimini and there is a zipper for a connector to the top of the windshield. This rig shown here though with side curtains and all is what I need for the squalls that pop up all the time here in the Gulf.
