Put an advert in the County Press etc for a computer technician and you should be inundated with work as long as your hourly rate is reasonable. There is always a shortage of decent PC sorter outers.
I'm told that there's a folk club at Shorwell and a session/club at Gurnard. You can always get the ferry and go to the Folcsle at Southampton.
There always used to be plenty of cheapish holiday flats for rent in towns like Ryde, Sandown, Shanklin and Ventnor but you have to be out for Easter when the rent soars and the grockle return.
Good luck.
