I'm assuming your sister has a minister lined up- but if she doesn't, my husband does weddings on the side.. he is a Baptist minister, but you don't have to be Baptist.
He's done many weddings and really enjoys doing them.
His number is ###-###-#### (he is camping with our 3 sons right now- he'll be back this evening).. Joel is his name.
If you have a friend who can do the cake that will save a ton of money....our cake was gorgeous and fed over 450 people. My friend only asked me to pitch in $20 for the ingredients... wow. What a deal! Also, you don't have to feed everyone. An afternoon wedding at 2 or 3 p.m. calls for cake and punch, and a few finger foods at best. I don't know why people think they need to spend $10,000 to feed everyone.
Remember people are there for your sister because they love her and want to wish her well. People with good hearts expect to go, bring a gift, and enjoy socializing. Being fed should not be at the top of the list.
A great photographer, a beautiful dress and setting, some pretty flowers, and bingo... you have a beautiful occasion to remember, and money in the bank left over for a first down payment on a house!
Good luck. Sounds stressful, but also sounds like a lot of fun!
