ELISHEVA,
I have been programming perl since 2002-07-11. I have intentionally never worked as a programmer as my primary vocation for various reasons that are not germane to this thread. I have also done some freelancing at various points during that time frame and have found that it can be a very strange and dangerous market. I appreciate this thread and have already pointed a few people to it. Here are a few more links you may (or may not) want to consider adding.
I shamelessly updated this node because it originally only included one link (which you already had listed).
