Since you want a 3'x3' surface, I'd recommend looking at the official x-wing playmat. AFAIK, it's made of the same material as TCG playmats and should provide a pleasant surface.
Looking at it right now, I'm not sure I can see the value. Your mat is pretty similar to the Official FFG Starfield Mat. Both are made of Neoprine, which is probably the biggest complaint against FFG mats. Minor adjustments to the miniatures impacts this game more than others, so the slick surface can be frustrating to play on at times. The FFG Mat can be used for premier events, yours can't (unless the TO says it can). And most importantly, I can get the FFG Starfield mat from Amazon for ten dollars less and quicker shipping.
I don't mean to be discouraging, my criticism is meant to be helpful. I think you'll need a few adjustments to appeal to the X Wing community, but there is definitely space in this game for a better mat. Best of luck with the project!
The ships are 1.0.
This is the mat -- it's in virtually new condition:
