MS Access update and improved accessibility

1) We have a client tracking database that was built on MS Access 2003. We need someone to update the database to the most current version. In addition to tracking, we need to be able to generate reports based off of the data. Everything is built, but it's extrememly outdated. We need to make sure no functionality is lost in the upgrade. 2) After the database is updated, we would like our managing staff to be able to view reports and numbers real-time remotely. Ideally, this could be done on an iPad or other mobile device, as they travel a lot. 3) We also have a lead generating website (currently written in PHP). We need to be able to push leads from the website directly into the Access database.
