fresnel lens supplier
look at 3dlens.com
They have several different sizes in the large fresnel lens section. You need something like 220 mm fl and also a 330 mm fl, (in optical acrylic) for a ~300 mm fl projection lens.
They will also have a 550 mm fl fresnel soon, in case you will be using a long-throw projection lens. (ie. ~450 mm fl)
