Hi, I am American, Boston-based programmer who nowadays works for pretty low offshore-competitive rate. I had extensive C++ and threads experience at Stanford (most notably, we implemented our own small Unix like operating system there) and also did some work in it later on. I would be happy to work for your customers either remotely (via continual Skype support) or onsite in America. I would be happy to discuss price for your project in more details after seeing the specs, and chances are I can do it much faster and cheaper than 30 days because I usually work very fast. Cheers, Michael
