That is currently what I am doing... I'm working as a class 1 lorry driver essentially taking home 21k year which is about 27k gross... Just make sure that your earning enough before saving. Typically I'm saving around 5000k then doing sections of my training. So for instance my ppl + night rating is going to cost all in around 8100 inc landing fees and equipment... I want to start this training in good weather so I'm looking at March. I'll use the 5k plus a loan to cover the rest so that I don't have to stump the rest of the money straight away.
Pay the loan off as quickly as possible then start the next step which for me is atpl study + 50 hour building ....
Lol basically just do a business plan and try and justify costs and schools.. And the end goal....
For instance I know a school who provide an awesome course with well written reviews not in this country who are charging 17000euro for MEP(L) + ME/IR + CPL under CAA UK which around 13k in sterling at the current exchange rate this include landing fees
...
It beats paying 26k for the same thing in the uk that's really the best deal I could really find and that was multiflight at Leeds :o
Good luck
