Yep I hate to disappoint you but you are going to need it all - CPL, IR and at least 500hrs.
Go and do your flying instructors rating and get a job that way. You have got to be looking at at least £30,000 for all. Then you can start building some hours.
It may take some time - but if you are young - you don't give up - and you keep looking forward - you will get there - it just might take a bit longer than you had first appreciated.
