Limo?

I am getting married on Jan. 4,2003. I have a 20 person wedding party. My Fiance is in Centereach and I am in East Islip. I want the guys picked up first dropped at the church, which is in E.I., then pick up me and the girls and bring us to the church.The church is at 3:00 and the reception at the Meadow Club is at 7:00. We also would need to take pics(hopefully at Dowling). What is my best option and cost? Thank you so much!
