HELP WITH DYEING WEDDING DRESS IVORY OR RUM P

I have purchased off of Ebay, a most beautiful, brand new gown of satin and tulle and am wanting to wear it for my June 19th wedding. It should arrive in 2 or 3 days! The only problem with it is it`s white. I want to dye or color it either ivory or rum pink. (This is my second marriage and I have some very old fashioned relatives, so a white dress is out of the question!) I know nothing about this sort of thing, but am a good student, if someone could give me directions on how to go about doing this! I have called most of the dry cleaners and alteration shops in Kansas City and nobody will dye it. I had no idea how hard it would be to get this done. I really love this dress and will be heart-broken if I am not able to wear it!!!!!!
