If you are at this stage, best carrier-wise option actually is to go to CTC. It may sound disgusting , and a rip-off but this is one of the safe routes to start your carrier if you are good. What they do they take 7-8k £ and sell you a JOC as well (which isn't oficially needed) but then if you are good, they have the connections for various UK and other airlines and is highly likely sooner or later to be called for a nice bonded job for a UK operator. I haven't gone there myself and I am not advertising them, its a real shame the industry works like that (only those people get looked at) but unfortunately this is the path that seems to work for a lot of people.
