What UK translation agencies have regular work?

I am a person with a little training in a lot of areas, one of which is French translation. I haven’t done it much in the last few years, but before that I did it for a few years working for charities and government.

Recently after moving to Europe, I decided I would like to try to make a go of it doing freelance work, but the one agency I’m with here doesn’t have regular work for the Fr>Eng language pair. Does anyone know of any reputable agencies that pay in UK pounds or at least Euros that have regular work for Fr>Eng? Any advice about making a living doing it, because the rates they seem to pay in the UK are often really low? I don’t want to have to pay them to register.

And lastly, what sites do you use when you’re stumped on a word or phrase and need an answer quickly? Thanks in advance!
