Back to School
With your business/economics degree that you mentioned then JB007's advice is spot on. There are several part-time executive MBa/MSc courses available at accredited UK based Uni's. Many of these courses qualify for various gov relief schemes.
These Uni's are well known in the industry with leads into the airlines, leasing houses and manufacturers; they're well connected when it comes to placing new grads and finding a job is rarely a problem.
This is a much better route than taking an entry level job and would open up numerous, rewarding career opportunities in fields you never even knew existed.
All you have to do is explore the option.
All the best to you.
