Answer by Linda Whittern

 It's difficult to advise, not knowing your range of skills and background.  Some general points though:-
 
You'll probably need to concentrate on working for companies that do business entirely in English (eg those serving the expat communities and tourists - elder care providers, holiday companies, insurance companies and the like) until you become fluent in Spanish. 
 
Employers generally prefer to employ teleworkers (you'll be a teleworker) living near their offices rather than in another country.  Some British, US or Dutch employers, though, will need teleworkers based in Spain to assist the customers or suppliers they have there.
 
Please contact the British and American Embassies in Spain and ask whether they can provide you with any information about UK and US companies (1) serving the expat market; and / or (2)  engaged in supplying or buying from Spanish companies. When you get hold of that information, look up each of the companies on their own websites and see whether they might provide any employment opportunities for you.
 
It's possible you might be able to work as a remote teleworker for an entirely UK-based company, but with unemployment being as high as it is, the chances are very slight.
 
There are a number of teleworking sites and general sites such as www.workingmums.co.uk that might be able to provide you with useful contacts.  Try the following for starters:- www.jobrapido.co.uk/teleworking ; www.work-at-home.page.co.uk and www.homeworking.com .  Good luck!
