OP, internships are certainly one way to approach the industry. Obviously, your circumstances are somewhat different - if you can't go abroad due to family commitments then signing up for an internship may be off the cards as well, particularly as you aren't doing a translation undergraduate degree. You may want to consider doing some work on a freelance basis, if you feel able to. A lot of it is about networking anyway - get to know the right people and things will come your way.
