You can have an inexpensive wedding!
I got married 4 years ago and we spend $3000. Our biggest cost was the rental location ($1000). I purchased flowers from a farm in 5 gallon buckets and my friends helped me put table centerpieces together in old mason jars. I got a local cake shop to bake us a very simple stacked cake with very little decorations for $100 and then I put fresh flowers on top. Grocery stores are also a cheap way to go for cakes and food. For drinks we had the caterer bring ice tea and lemonade and then we bought a keg of beer and bottles of wine from Costco. Dinner was catered and was a chicken BBQ cooked onsite (for about $8/person). There are so many things you don’t need you just have to decide which things are really important to the two of you. I also scored some cool stuff on EBay. We had about 60 people at our wedding. – Good luck!
