I would guess the highest leverage thing you could do is open source some of your work on Github as samples to show potential employers. If you are just getting by your top priority should probably be to find better employment ASAP. Making money off little utilities like this is almost certainly going to be tough going.

Have you gotten any feedback from people on these projects? If you get feedback from people that might give you a hit as to whether they might be willing to pay money for such things.

When you put a lot of time into something and are understandably pleased with the result it can be hard to look at it objectively and you are likely to overvalue your work relative to someone who isn't invested in it. Maybe just look at them as a stepping stone learning experiences to bigger and better things.
