Others have suggested getting work as a sparkies' mate or suchlike, but if
you're not particularly driven towards electrics you might consider doing a
bit of labouring on sites to get a feel for what jobs do interest you. Just
being around on a site should give you opportunities to chat with different
trades and, if you get on with them, maybe try out different work. It should
also help give you a measure of your own capabilities.
When I was starting out working as a plumber and general tradesman I had the
good fortune to have a job working with a seasoned pro chippy/builder for a
week or so dismantling and rebuilding a large shed. At first I was afraid
I'd show myself up as a rank amateur, but as I found I was able to pull my
weight I gathered confidence and realised that, whilst fine cabinet making
is proabably not my vocation, I can do a useful and worthwhile day's work.
I'm sorry, I have no idea how you go about getting site work, but I expect
going up to someone on a site and asking would be a good first step :-).
If you find you don't much like site work in itself but would rather be
going out and working on your own there's plenty of opportunity to make a
living doing this, once you know what area you want to work in.
As for training, if you've done As and Uni you'd probably find the pace of a
full-time course at a Tech crushingly slow, but short concentrated courses
for existing workers better (I'm basing this sweeping generalisastion on
what I know about NVQ plumbing courses versus the ACS gas training).
