But cant find any Lisp job vacancies (conspiracy?). Probably the only real way to program Lisp is to start your own business, but then you wont have time for Lisp and will've to hire Java monkeys, because you wont find lispers. No way!
looking at the hits, here's an example: http://lispjobs.wordpress.com/
There were also a few companies that hire Lispers, but you should be able to search the Internet yourself.
Personally, I think starting your own projects is the most interesting choice, but that's only if you can find anything worthwhile that you would like to invest your time in...
