british sign language?

I would like to learn british sign language and become a translator… how realistic is this through doing nightschool?
how long would it take to learn the basics and how long would it take to become good enough to become qualified?

What kind of jobs are available through learning this (i dont want to teach) and what apy can be expected
is freelance an option?

(this isnt a whim i’ve been thinking about it for 4 years now and about to take the plunge, just need some advice that its the right thing)

any ideas advice would be a great help

thank you
