I am doing a cake that is not a wedding caked but stacked.
It will be a three tiered cake with fondant decorations and a fondant bow topper.
Enough to feed about 75 people
What would you guys charge for this????

To me, this is a difficult question to answer. My pricing is based on bakeries in my area. For example, a 3-tiered cake in new york is going to cost a heck of a lot more than in po-dunk, louisiana. Maybe some will give you pricing, but I would recommend you see what your local bakeries are charging and base your prices on that.

the same as you would for a 3tiered wedding cake.

ditto.

It's the same cake as the wedding cake. Makes no difference to me whether it's served at a wedding or a birthday. Same work for me. Same price to you.

I don't care if a customer serves my cake for a wedding, a birthday, or a Super Bowl party.. they all cost the same per serving.

And when you say fondant decorations, fondant decos with this amount of work? http://www.bakedecoratecelebrate.com/images/projects/colorscollide/colorscollide.jpg

Or this amount of work? http://www.cakejournal.com/wp-content/uploads/topsyturvydvd_edited-2-212x300.jpg

Big differences to be factored.

Sorry...misread your question. Disregard my answer.
