Looking for low-cost PPL training

[welrifai]

Hi all -

I have done about 3 hours of training at Willow Air at SouthEnd airport south of London... wondering if there's a lower cost way of going for my PPL. What sort of qualification does a someone helping to train me need? Can they log hours for it? Any ideas on if it's possible to find someone who'd want to split the costs, or forums where I can go about searching for this special person :-)???

Thanks,

W
