I really need to know about pricing. Is there a chart somewhere on the wilton site?

I would love to answer your question but I have the same one and was going to write a post here in a couple of days. So here is a bump for you

The best thing to know before you can price your cakes is how much money you are putting into your cakes.

It is hard to have a chart that works for everyone because different places have different going rates. A small town is not going to have the same cake prices as a large town.
