Web App for Scheduling Online Lesson (UX design model in description)

Our time is looking to have a Web App developed for our online language school. Here you will see a simple UX design model of what we are looking to create (note: the design model does not imitate all of the interaction required but does give a clear idea of what we are looking for) [login to view URL] If you have any questions about what we need please do not hesitate to send us a message. We would love to hear proposals with comprehensive quotes on what it would take to build this web app. We look forward to hearing from you all!
