Look bucko, I will put this as nicely as I can. A complete rubies suit runs $89 on ebay. Individual masks go between $20-30. If that is a serious amount of cash to you, then prop/costuming of any kind is not for you right now.
You did not say you were looking for advice, you simply asked if someone would give you a mask. If you knew ahead of time that someone would 'respond like this' then maybe you should have chosen your words with a little more care.
There are all sorts of cheap ways of producing an amazing looking suit, but they all require some time and effort, and ultimately, cash. If $100 is out of your reach, then my advice to you would be to comb through this place for info on foamies, cardboard armor and everything similar, and you will be able to do pieces here and there when you have a spare $20. In time you will have a full suit.
