Sponsor open source work
The web is based largely on open source software, and working in conjunction with open source projects can be an important part of the develop and maintenance of your software systems. I have extensive experience in developing fixes and features in open source, and work I perform for clients in open source projects is discounted significantly.
Open source projects I've worked with to develop features and fixes for clients include Apache HTTP Server and related projects, several plugins for Django CMS, and others.
