You might also try some audio drama groups online. Most are free to join, and non-paying gigs.
Dream Realms (dregold.net) is a smaller one, and Pendant Audio has a lot going on too. Plenty of others out there as well.
You may also want to do some volunteer reading - several groups for that too, depending on your city.
