Might be a similar company near you.
I had a similar screen I made that velcroed in place on my '98 Ranger II. The problem was the screen was too stiff. What I would recommend is making one out of really flexible screen (like for tents) and, instead of a zipper in the center, make two panels that overlap in the center. Make it so it hangs down below the door with some weight hemed into the lower edge. Then just part the overlapping screens and let it wipe the mosquitos off your back when entering.mhskog said:For anyone who cares we started with this

and cut it down to fit the door mounted the magnets, it's solid no middle seam,so to get in you pull one side down, maybe not as easy as a door but has been very effective, we just fold it up and put it in the storage bin when we are not using it. less than $20 and it's worked great
