Liquid Hockey,
This may seem harsh, but quitting college to become a pilot 'not having a clue where to start' is absurd.
I assume you can quit because you've got £55k in the bank for an Integrated ATPL course? If so I take it back. If not, why not just continue for 1-2 years (or how ever long you have left) just to apply for sponsorship. Even if unsuccessful with sponsorship get a good job and start saving.
I know you seem to have made up your mind but please think again.
If you are so sure however, start reading up on the modular route to a CPL/IR which will cost you around £30-40K (thats the cheaper option).
