Transition from Wordpress to SquareSpace

My website (newnaratif.com) is looking to transition from a wordpress-based installation to SquareSpace. We simply wish to import the current design over so we don't need design work. What we need is a technical consultant who is SquareSpace certified and can help us with technical questions about the transition. As a membership-based service, we would like someone who is familiar with SquareSpace's membership subscription system, paywall, scheduling, and events management systems. We're also interested in increasing interactivity among between members so we would appreciate any advice about how that can be facilitated.
