Sounds like an interesting project. I must admit, I am intrigued as I am a Super Mario fan.
Looks like the mask you described would run about 120.00 plus shipping. I would cast it in thick rigid neoprene, so it would be very resilient, and since you need a fairly flawless surface I would opt to finish with automotive paint. That would also give it a very polished, ceramic look. this could be completed by August.
We do like making things in volume, so if you were able to find four or more others to purchase the mask we would provide yours at no cost.
Let me know what you think. Thanks for your inquiry, and if you have any further questions don't hesitate to ask.
What I am going to ask is that instead of giving me my mask for free, to instead split the "free" between everyone involved, so we all get a discounted price. I haven't emailed him back yet (doing that after this), but he is a great guy and chances are he will agree!
What I need from you is to know who is interested, and who definitely wants one, and I need to know ASAP!
Thanks, and crossposted to rapierce and shybeta
