Consider this.... You are having great success at ranking your own websites. Are you making any money from them? If not, try adsense. It is very easy to make money that way.
You could start building sites for yourself on weekends, evenings and days off. If you work diligently your sites will become better and better and your income will rise. Soon you could be making more money from websites than your job. Once your websites make twice as much as your job and you have some nice money in the bank and your house paid off - then quit the job.
