Is there no way you can get a degree at all? Even if you got a lower second/third, you can go into teaching, and their salaries start at 24K+ which is nice. A degree will give you a boost in whatever career path you may want.
That being said, one of my friends works in the Government (MI5 or Mi6 I think), and started with a salary of 18k, with purely just A-levels and GCSE's to show for it. There are numerous occasions where people can be successful, I mean Peter Jones, Alan Sugar, Duncan Bannantyne and the majority of those business tycoons don't have anything past GCSE (or 'O' Levels back then)
