If you go back to the IT industry and stay current you will probably have a chance of a job with the hours you've got if you are under 30 and get lucky.
If you do the FI rating you will build hours quickly and enhance your CV and more importantly your flying ability. BUT YOU WILL BE SKINT!
Personally I took the instructor route..........
I've never been more skint........
I've never been happier......
The choice is yours
Good Luck
