Tiffany blue and chocolate wedding?

I need some help! I'm looking for square tiffany blue boxes in various sizes (too spray paint tiffany blue for centerpieces) and I want to buy them in BULK... ?? Any ideas? I also wanted to know where I could find colored card stock, plus cute accessories to make my own invites-- but I don't want a kit, cuz I want to get creative with it. PLUS I need tiny tiffany blue boxes, or just tiny paper mache boxes to put favors in-- big enough to hold 2 sheets of on candy (its a 1940s inspired wedding as well) AND any other ideas you might have! Thanks! Sorry that was so many questions in one lol
