Well, one thing is that at least here in the U.S., its common to work on an hourly rate, so you set your rate and then maybe give an estimate of time but you aren't tied down to a monthly salary (which is especially important for a freelance project where the client may change the scope), have you tried this approach? That said, working remotely as a freelancer doesn't always provide a whole lot of stability, if you could move somewhere else in Europe where software development is more appreciated that may help your career, although you could try some of the freelancing websites to make some quick money, I know the average rate on some of those for a developer can be as much as $15, I think, so that may be more than what you can make locally
