If your budget is limited, and you particularly like piston engined aeroplanes, can I suggest looking at the route to being a microlight instructor?
It's an okay living, relatively accessible, and very much about being enthusiastic about flying little aeroplanes.
A share in a microlight would allow you to cheaply build hours using either an NPPL or a JAR licence, then the instructors course is much cheaper than the JAR CPL course.
And you can always switch later and upgrade, at 31 you're not exactly over the hill.
