Adjusting Wednesday night service

I'm am a relatively new pastor at a small, rural, traditional church. We average about 65-70 on Sunday mornings...we have very few youth...we have a handful of children. I've been at this church for 22 months, and this is the first time that I have served in the pastorate. I was a college minister for more than a decade leading up to this. When I arrived, I kept the Wednesday night service as it was, and it's pretty basic I guess (my wife and I hadn't attended a church that had a Wednesday night service since I was last a youth minister in 2002).

We have 3 songs to open...we go into prayer requests and pray through them (either break into small prayer groups or pray for each one as mentioned or come to the front of the church as a body and pray as people are led)...then I have a short message that is usually ~15 minutes. Our timeframe has been 7:00-8:00.

We are on the verge of starting an Awana ministry on Wednesday nights, and that will run from 6:30-8:00. So, that adds a half hour on the front end of our service, and I'm trying to figure out what to do.

So I guess my question is...what do your churches do on Wednesday nights? How long? What works...what doesn't work? What advice/insight/wisdom can you offer a first-time pastor at a small, traditional church that values Wednesday night services?
