It's not possible to train in Scotland for the kind of budget you have.
All of the Schools are moderately priced for the UK, in fact I might go so far as to say it was quite cheap to learn in Scotland but knowing how much it costs to get them into the air the minimum you will pay for the flying hours alone on the PPL course is about 6500.
I think you need to think carefully about waiting a little while longer and saving some more money - you don't have enough yet.
