Time for the facts.
You will have to do the Basic course, followed by the ADI course. and because you have no prior ATC experience, its the bare minimum requirement.
This process will take around 18 weeks and cost you around £16K, plus VAT, plus accommodation and subsitance.
After that, you are very low on the employability scale, you'd have to do the radar rating to stand the remotest chance
of gaining employment (another £12k + the rest).
All are very intensive courses and there isn't the remotest chance that you could do them and remain in full time employment.
Additionally, it's extremely unlikely that any airport would take you on and sponsor you, they have many of their own staff who are streets ahead of you in terms of experience who they'd far rather invest in.
Chilli is spot on, I am afraid you are too late and shouldn't risk your money.
Take a little time to reflect upon your possibilities and invest elsewhere
