When should i start my wedding??

We have to be out of my wedding venue between 9:30- 10:00 pm it is a outdoor wedding June 6th, the sun starts setting at approximately 8:11.. we paid for extra lighting because it’s absolutely beautiful. So we know we want the wedding to go on into the night. My fiancé wanted to start the wedding at 6:30 pm but after I got to thinking I feel like that’s a little late due to the ceremony, sunset pictures and eating then cake cutting i don’t see how that would leave much time for anything, I feel like It would all be rushed... any advice? We are also hoping a lot of people will be gone and the last little bit it can just be the bridal party/close family.
