Honestly, it's not my cup of tea, but the most effective way is through church. Find the biggest, most prominent/ active protestant church in the town and start regularly going to service. If you attend by yourself, you're sure to be noticed since it's a small town, and thus meet people who will know people who will know people. Protestant faiths are more known for their emphasis on "social networking"/ social/ community based practicing of their faith, than let's say Catholics. For example, youth groups in average protestant church tend to be much more active than the average Catholic churches.
