Please Help

I live in the Baltimore-Washington D.C. area and everything is high here. I am new to pricing my cakes and would like an idea of how to price a Sponge Bob cake (I looked at the matrix already). I priced the ingredients and added a reasonable time for labor, does that sound correct?

My idea is to make Sponge Bob out of RC w/fondant and have him sit on a sheet cake w/sea elements around him and happy birthday on the front side.

This cake would feed 30 children so I thought a 9x13 sheet cake with Sponge Bob to scale will work. Is it too small for 30 people?

PLEASE! Any advice on scale, design and pricing would be greatly appreciated. This is my first big break, the parents and grandparents are well known and respected in my community.

Thank you,

Hi and welcome! Please let me be the first to say, in the most friendly and gentle way possible, that it is not legal to sell a copyrighted character unless you have obtained the rights to do so. Your cake sounds great, but just leave off the Sponge Bob and have your customer purchase a plastic topper or toy to set on top of your "seascape" cake.
