Don't focus on the competition. Finding your first job is always super tough. I know it seemed impossible when I was in your situation. (I felt so desperate!), but somehow things work out in the end. In the current economic climate, it might take a while, though: don't be upset if you don't get a career job immediately; it can take a year or two sometimes.

You have the grades, so stick with your current course. You do not need a computer science degree to build a career as a software developer. Practical hands-on experience counts more than qualifications.

I believe that a multi-skilled / cross-disciplinary software engineer can expect to earn more money over the course of their career than a straight-up developer. The skills shortage (and therefore the demand) always seems to lie in-between disciplines.

Software development skills + math + business gives you a possible (eventual) avenue into quantitative development in the financial industry, which can be a lucrative career path should you chose to pursue it. (Be prepared to spend a significant amount of time (10 years?) building up skills prior to making the move, though).

Once you have finished your degree, you might consider doing a software-oriented masters degree, or spend 2-3 years with a small company picking up the basics. Your multi-disciplinary skill-set should stand you in good stead. If you cannot find a company willing to hire you, start one! Even if it does not work out, that experience will be golden. If you don't have any ideas, ask in this thread. I have a ton that I am never going to pursue. I am sure that others will pitch in as well.
