I am currently developing a product design, development and marketing company, located in the San Francisco, Bay Area (California, USA), which is focused on developing sport/work related clothing and similar consumer products.  My initial need is to identify companies that can develop complex products, based on proprietary designs, to be marketed with private labeling.  I am seeking OEMs/ODMs (sewing and product development contractors) for sample work and small production private label sewing projects.  A potential contractor must be able to develop complex vest garment samples, from renderings and design documentation.
