The problem is: you are too cheap. A programmer in Europe can earn much more than 12 euros an hour, but you're not charging more. It makes me wonder why. The only reason I can think is that you're inexperienced, just starting out. That doesn't tally with the statement that you can do any kind of code. I've been programming for many many years and I would still be wary about saying I could do 'anything'. There are lots of hard problems in Computer Science. Mobile app development is not one of the hard problems, so I would wonder why you would exclude that and not, say, massively scalable cloud computing, 3D rendering, etc.

I would suggest you be a bit more specific about what tasks you want to do, and double or triple your prices. ;-)

I wish you very good luck with the company though!
