Custom Plastic

I Would Like To Make Chocolates With A Design On Them, Which Would Require A Mold To Make Them In, But I Can't Seem To Find Any Place That Makes Custom Molds For Candy-making, Because The Top Zillion Results On A Web Search Are The Same Old Places Selling Heart And Bunny And Santa Shapes Molds. Does Anyone Know Of A Website Or A Brick-and-mortar Store That Will Make A Plastic Mold For Chocolate Candies? I'm Not Looking For Commercial Uses, So Preferably Something Not Outrageously Priced.... Thanks!
