Automatic import of administration data into joomla

We have a joomla website which needs the following option: We use Pimexonline organizer to keep track of our client data, and we want to import this into Joomla with csv function that is already into Pimexonline. Thereafter we need to be able to process it automatically into some tasks. This is what we need: 1. The name, e-mail and another textfield needs to be imported into the usermanager, whereby the other textfield will be the password of the user 2. These users have to get a 'license' into a payperdownload module, with the expiration date that is in the csv too. 3. All these new imported users have to get a mail with a standard pdf, which has a image in it and the 'expiration date' of their license 4. In addition: we want to convert the csv into a kml file, which we can import into Google maps. So in short: there are three, four or five columns in a csv that needs to be imported by the client into some software you design. This software has to make sure tasks 1-3 are done. If it's possible to find a solution for point 4 that's a bonus. Let me hear from you!
