It seems to me that you should be looking for work in a recording studio, or maybe teaching music technology to Further Education students on Btec Courses or in Sixth Form Colleges, while you're finding your feet as a producer and/or composer.
You might be able to compose for student films, so perhaps you should do some research into knowing who the emerging student/young film directors are. You'll gain experience and hopefully grow with them.
If you're good with music technology, perhaps you can assist older composers who are uncomfortable with using composers software for preparing their scores for musicians to play from. You can find out about such composers through the professionals that work in the administration of making music for film... ie in Film production and Music publishing companies. the same applies to TV.
In the world of theatre, your skills might also be helpful, but quite a lot of music in theatre is played live.
Hope this advice is helpful.
