Challenging Flex / Flash-Builder project for visualizing data structures

I need a highly skilled Flex developer to work intensively on a visualization engine for data, using a customized treemapping algorithm. See [login to view URL] In addition to the core engine, the project will include several data layers that will be overlaid on top of the visualization and a simple communication protocol with a server (to fetch the data used for the overlays). You will not need to deliver anything except the client-side. Before sending you a detailed spec that will allow you to bid I will send you an NDA to sign, but first I will need to make sure there's a potential fit. For that, please post a comment with the following: • describe your experience in Flex development • include 3 direct links to some of your most impressive work till now (at least 1 of them should be to a sophisticated Flash project) • describe your experience in working with non-trivial algorithms • what is your availability? (days per months, hours per day, when can you start, etc) • although this is a pay-for-deliverables project, just for me to get a rough sense of pricing, what would be your fee per one month of intensive full-time work? Thanks
