To be honest, there are many areas open to you. At the end of the day, you'll still have to consider how to pay for your training. In the event of not obtaining sponsored flight training, you'll have to pay yourself. If you're heart is not in ATC, then you can't be sure they would train you. As far as I know, there is little flying training for ATC, apart from a jump-seat on a jet at the end of training to view ATC from the pilots perspective. I don't know what ATC controllers earn, but I'm sure there are other means to fund training in a shorter time period. I've no idea what graduate opportunities are like in the current economic gloom, but with a first you should find it quite easy to secure a place in a management consultancy, or in banking. These will give you a substantial income, requiring you to work for 2-4 years to fund an integrated training course.
