Need Chair Covers,Sashes, And Centerpieces

Hello brides! i`m looking for 100 white folding chair covers, lavender sashes, and 30 centerpieces. I`m wanting the tall eifel tower vases with the white ostrich feathers and the lighting. I also need the mirror bases. My wedding is june 2008, and i`m looking to get as close to 30 as i can. If anyone can help me find these as cheap as possible please help me. I`m in the lubbock, tx area. Thanks a bunch!
