Belt Pouch

How can I get a water and shock resistant belt pouch Palm Zire?
I have a Zire 72 that I depend on the indoor and outdoor activities, so I need a case or bag: 1. It is of 2 weatherproof. Shockproof 3. They can be worn on the belt 4. Not bulky. Nothing I've seen in the line meets all these requirements together, so I need suggestions on how to line the inside, what exterior material, how to attach a durable belt clip, and how to make a tight seal. Doityourself'm the kind of person, so do not fear challenges handwork.
If you find or make one, the marketing potential is enormous. I must say that you are a demanding person. Here is one that suits your # 1,3,4 http://www.waterproofcases.net/wallet1.html To meet its # 2. Condition of shock-proof, maybe you could try a little TLC, or if you play football with him on the belt?
