In terms of design, yes visual design, especially for smaller companies, where they may not have a UX role, and you could try and incorporate it as well. Software testers half the time don't need to be able to do any coding or understand too much code, it depends on the role. What they are really good at is finding edge cases, testing workflow, giving suggestions as to what is confusing, and what worked and what didn't work well. - Just a thought, though that one might be harder to transition from.
In terms of grants, I got an internship with a company through a Callaghan Innovation Grant. So they basically gave money to the company, to hire and pay someone to do 6 moths worth of UX work on a project. Sometimes if a company can get help funding you, they might be more willing to take you on board in a learning capacity. I was basically working for this company for free, and they got 6 months worth of work out of me :).
