Teddy,I learnt at Leeds,many years ago now.Your option there is Multiflight,who are a perfectly good organisation.The downside of Leeds is that it is busy,and expensive,but a good environment to learn at.You don't say which side of Leeds you are on,but I fly at Sherburn now,which is alot cheaper,and has good aircraft availability.It is possible to get a ppl in a matter of weeks,but this would be full time,and heavily weather dependent.Most 'leisure' flyers would take approx 50 hours,and it took me 10 months to complete.As regards cost have a look at the relevant websites,and multiply the rate by at least 50! Wherever you do it,I guarantee you will not regret one minute!
