Remuneration reqs

My 2017 monthly gross contract salary was 1050E plus performance bonuses and as a German HRM professional advised me in London in 2012, I'm available for basic salary since my operating/living costs are low. I've had a 2014 offer to work for UK federation in Brussels via freelance, I prefer fixed term employment contacts of even eg 1 month duration than freelance in the EU, too bureaucratic alas. Not looking for a long term contract per se.
