Timeline help

I am getting married around 6pm and want to take photos before the cermony.

What time should I have my hair/makeup done?

Just an estimate:
3:30 - 4:30 taking pictures before ceremony
2:45 - leave prep location - travel to take pics
1:00 - 2:00 makeup
1:00 photographer arrives to take pictures at hotel/prep location
12:00 - 1:00 hair
