Where can I get bulk sea gl, stones, decorative, gems, marbles, or beads?

I need to find the cheapest bulk sea gl, decorative gems and marbles, gl stones or something of that sort. I need pink (not pale pink, hot pink or fuschia) and green ( a limeish colored, not dark) for wedding decorations. I have about 10 large vases that I want to put alternating layers of pink and green and artificial flowers will go in those....the I have about 20-25 small votive candle holders that I want to put more gems or whatever in them to hold candles. I need quite a bit so if anyone knows any good websites for buying this stuff in bulk it would be very helpful...I've searched for websites without much luck and anything I find on ebay, there is not enough product; I need big bags of this stuff! Thanks!
