Help!

[FayeF20]

Afternoon,
I am currently working for a large investment bank in facilities administration.
Basically I feel I could be more usefull elsewhere. I love working with people and have great communication skills, I have always had a customer facing job but this one isn't interesting enough or very highly paid (living in London-every penny counts!).
I didn't go to university but have 1 A-Level and 2 AS-Levels (and 10 A-C GCSEs).

I cannot afford to study but am more than willing to train on the job.
I know I am asking a lot as you do not know anything about me (other than that stated above), but...

Can anyone think of a job that would be perfect for me?

Any answers appreciated!

Thanks
