Data visualization application for android (others later)

Develop a mobile application that will- -Use an existing toolkit to access a standardized API to authenticate a user, and then retrieve indutry-specific data -display the data in a collection of forms -display some time series data in a graph. several values can be graphed simulataneously -allow updating the graph data in a polling fashion -graph data may be over a long period - point and drag to scroll the data graph -cache the connection info so it can be auto-refreshed later without having to re-enter login data -allow user to store pre-selected items in a list, for ease of re-loading later -If the data proves to be too large to query every time, we may optionally store it on the device I'm sure there will be more questions about the requirements for this project, so feel free to message me before bidding. I will add the clarifications that I can here, but some features of the application I would rather discuss in messages instead of in public. Previous work on a similar project is a huge plus, please be ready to show examples of your prior work. Im hoping to keep the cost low on the project by utilizing your prior experience building similar applications. I also need the source code for the project. The plan will be to re-hire you to add new features in the future, but we need the source code here in case we need to do a quick bug fix or similar. If you plan to use any closed source components, please specify what these would be in your bid. Thanks!
