Promotional Miniature Plastic Trash Bins

I'm seeking an expert in plastic manufacturing with a real creative flare, to design promotional miniature trash bins. These are going to be about 5 to 10 cm in size, making it essential you have expertise in working with small scale production. A solid understanding of making functional plastic items is important because although these bins are mainly promotional they should still offer a level of utility. Your experience in ensuring a high-quality finish on all products would be beneficial as well. Please provide examples of similar projects if possible.
