Microsoft Office Dcom security configuration with Php

We want to employ a person able to configure a com application from scratch, in order to have connection with web environment (php and iis).
Your mission will be:
- Oversee the creation of DCOM applications that correspond with the Microsoft Office Proffesional Plus package applications (word, excel and powerpoint).
- These applications have to have the correct security configuration in terms of permissions and identity of who executes them in order to be invoked from php through the "com" class.

- Finally, the PHP code must be able to perform a series of tasks, which will generate files in different formats (pdf, ppt, docx...) In this way, we will check that the configuration of permissions and identity was carried out correctly.
- The task of permissions and identity configuration will be performed remotely, guiding a developer of our company who will be the only one with access to the server.
