Wedding Cost

I am trying to plan a budget for my wedding and was wondering how much it would cost for the reception. I live in South Carolina and we thought about having barbeque but decided it would be too expensive. Instead we are only going to have finger foods and cake but no alcohol so that should cut cost. I was wondering what an estimate would be for about 240 people. We are going to have it at a different location so not everyone will show up and the catering and rental fees are free. I just need to know an estimate on the cost of food and some ideas on what to serve, including other kinds of beverages then alcohol or punch. Thanks for the help!
It will be near Orangeburg, SC.

I live in SC and I did the whole finger foods idea for my reception bc it was an afternoon wedding. I had about 125 people and I spent $250 on the food, so you could double that estimate. Sam’s Club will be your new best friend, find someone with a membership or invest in one yourself. As far as ideas for food, we had saucy meatballs, Danish wedding cookies, ham and cheese mini croissants, cookies, fruit, and sausage balls. As far as beverages, of course we had the sherbet punch, but it’s the South, everyone loves sweet tea. You might offer unsweetened or diet soda for anyone that is diabetic. Good luck!
