I'm not sure about volunteering opportunities as to volunteer you would need to have a decent level of Irish as you would likely be speaking Irish to the pupils and even teaching Irish classes. This could vary by college though and while some will be happy to allow you to turn up and help out a little, others may not see the point in you volunteering but not actually being able to take on much responsibility. You could phone up the various colleges and ask, that's probably the quickest most efficient way to find out. Depending on where you are based I also know of a few GAA camps that run through the medium of Irish and are happy to have volunteers of all abilities. It's called Campa Chormaic, they have weeks dedicated to pupils who attend the Irish medium schools and to volunteer with these weeks you need to be fluent but to volunteer in the weeks for all other pupils you do not need to be fluent.
But on another note many of the Gaeltachts actually do run courses for older pupils, some are aimed at university students who are training in teaching and need to have Irish as part of their studies but others are simply aimed at adults wishing to learn Irish. It's definitely worth looking into courses aimed at adults as you will get more out of it in terms of being able to socialize with others your own age and having the classes aimed at adults with a similar level of Irish to you.
