PPRuNe Forums - Starting training in Elstree?

Hi..
This is my first time posting here, sorry if I'm doing anything wrong, I'd just like to ask for some advice.

I've had the ambition to be a commercial pilot for a long while..
I'm now 16 and have just chosen the topics I am going to study for A-Level (I chose: Physics, Maths, Geography and Biology if your interested)

I was told that I would be best, whilst doing this, to do a Private Pilots Licence at Elstree aerodrome (as just another thing for my CV - as I've heard pilots jobs are very hard to come by)

I'm not sure if anyone knows/heard of it Elstree, but after that I was thinking of maybe applying to Oxford Aviation Academy, and doing the FO course.
However this would be very expensive and although I could fund this, I was wondering if there was another, maybe less expensive, way that you can suggest?

Also as a side note, last year I did my work experience at Luton Airport and have good comments from my supervisor. I learnt a lot from that week.

Any help would be appreciated, and sorry again if I’ve done something wrong.
Olly.
