Be very realistic on your budget.
If you get a job at 185 hours you will be exceptionally lucky. You could hold out to secure an offshore sponsorship if everything falls together perfectly.
To hurry things along, you can then attempt an IR. £25-35k depending on who/where/what. No guarantees
Alternatively, hour build to 250 and take the FI course. Part time work will come your way, and full time if you're lucky.
Nothing will happen quickly, so it requires a lot of patience and the ability to not only pay for your training but also sustain yourself with little or no income.
If you have any doubts, it is better to cut your losses early on. Its a lot of money and there are plenty of other exciting and varied things you can do with that money.
Age is on your side, but don't waste it on something like flying unless you are certain its your dream
Not a lot of utility work in the UK I'm afraid. Even less for a low experience pilot
