Wedding Cost

My mom is getting re-married and is having a very small wedding with only family. I estimate around 20 people will be there. My sister and I are planning on getting a cake as a surprise for her. How much would a nice wedding cake cost for this small a group?

I honestly think that a one tier cake will be sufficiant about 12in round but you can add a second tier for looks. I just got my quote from the lady doing my wedding cake. Its a 3 tier (12in, 9in, 6in) cake that will feed about 96 people (not including the top tier) buttercream basket weaving on the outside white with rasberry filing on the inside. She is charging me $150.00. I would go to a local grocry store or bakery. They have lovely wedding cakes and give you an idea about how much you would pay.
