I think Peir would be interesting and I think Joseph at SP could help you if Snow is too busy. I know Barneys did an interview with Walid al Damirji of By Walid but it sucked ass, it looked like they just sent him a questionnaire postcard. They carry his stuff at two of their stores. Beverly Hills and at their flagship store on Madison Avenue.
Joseph knows a lot of people and if you want to get some inspiration id probably go back Young N Hungry thread and look up some of the designers there.
