New to the forum...need some help

Hi everyone. I am the North American Marketing rep for a Brazilian company that makes men's and women's t-shirts using organic fabrics such as bamboo, organic cotton, and Cupuaco (an Amazon fruit). I am looking to open up the North American market. We have had good success here in Brazil, some initial and promising success in France. Any individuals out there with experience in getting products into retail outlets in the U.S. and Canada, I would love to hear from you with some advice. If you work in this field and are interested in working together, please let me know as well. Thanks for your time.
Steven
