www.sourceguardian.com - encryption software for PHP. Have been running this for around 10 years. This alone would be a very good 'wage' for someone
www.europeantenders.com. This provides leads for european government contracts
www.ukscrap.com. This is a referral site that we created for people who's car is 'end of life'.
www.rubyencoder.com. Similar to SourceGuardian. It's for encrypting Ruby source code. We had a need for this ourselves so created it
I run a few more also. I love the freedom that this has given me and the regular income allows me to play with what I'm interested in
