Here are some names of PCA churches in the general vicinity that your friend might want to visit. Except for some of the Pastors names, I don't know much about them. They are Willow Creek in Winter Springs, Covenant & Saint something in Winter Park, University right south of Oveido in Orlando, and Orangewood in Maitland. I have visited Willow Creek and Orangewood once and both seem to have RTS connections.
