Where can I buy black roses?

I know that there is no REAL black roses. I need some roses that are black, whether they are tinted or dyed black doesn't matter. I need a pretty small amount- around 20, but I could go up to 50 if that is the only way to buy them. Please don't give me any 'other options' or links to fake roses, or tell me that I can dye them myself. Also, please don't tell me to call my local florist. I just need some black roses that I can buy online. Thanks in advance. :)
