Ten Points to who can help- I need to find somewhere I can buy plastic ice cream cones for a yard display?

For my friend's birthday, I'm planning on buying a bunch of plastic ice cream cones (similar to the plastic pink flamingos people pu in their yards) and put them in her front yard with a sign for her 21st birthday. I have been googling and can't find where to buy them though! I've seen them used....we don't have a company that does it where we live so I was just going to do it myself. Please, please help :)
