Looking at the weather should really give you a clue! I had to give up full time instructing as the weather last year was so bad I couldn't pay the bills!
Also flying schools will still only pay by the hour even if you are full time. Very few are salaried although some will offer a retainer - generally the ones in the south of England.
Good look if you go full time and remember its not just the weather, its how busy the school is. If they have few students you won't fly even if its cavok.
If you want a salaried position you generally need experience as you are then looking at OATS, SFT, Cabair etc.
