Longitudinal Graph / Network Visualization of Email Data

I need someone experienced in network / graph visualization to help me do the following tasks:

1) Select a database to use (based on #3 and #4 below)
2) Automatically import information (e.g., sender, recipient, date, email subject, demographics) from an email data set of senders and recipients [note: I'll manually insert demographic data on each participant into the database]
3) Calculate a variety of network statistics (see: http://en.wikipedia.org/wiki/Network_theory)
4) Create a dynamic, longitudinal network visualization over a period of 2 months (see: http://en.wikipedia.org/wiki/Network_visualization)

Project is ongoing; expected to last between 6-12 months (the time period it will take me to complete the paper).
