How about getting some business cards made up (maybe $10 for a bunch if you design it yourself)?
Most local coffee shops, supermarkets, libraries, etc. have bulletin boards. Post the business cards there.
Most apartment complexes have bulletin boards in laundry rooms.
You can even go around to local houses and put the card through the mail slot or into the mail box.
I used to record the amateur hour(s) at the local coffee shop and broadcast them during the week. The artists would make sure that friends and family knew that they were being broadcast on the airwaves, and some would continue to listen.
I also went around to the local businesses to let them know that we existed. Some were willing to play the station stream as background music – that’s the advantage of Internet streaming, as listeners don’t need to be in the over-the-air coverage area.
If you get out into the community and let yourself be known, you’ll get listeners.
