One way to make a living in Open Source is to create a proprietory format based on Open standards with proprietory extensions. Here is an example. You modify and build a custom portal from an Open Source portal. Your tool creates JSR-168 or JSR-286 war files (open standard) with proprietory extensions. Give it a .portal file suffix. The majority of the format respects the portlet standard and the extensions make it proprietory. With some modifications from a professional it can become standard therefore interesting to the Free Software Community.
