I walked away in the dark ages, so others have much better tech info than i. we used to use valves then, remember them?
But, 2 things i suggest:-
don't do the free work thing. you are not doing yourself or anyone else any good. you will come to realise in this in time.
Also, it is always easier to find work when you are employed, not sure why, just is. then you can network and steer towards your goal.
Good luck.
