Wow, this thread certainly rings true for us, doesn't it?
I'm not sure why, but people seem to think if you don't have a "storefront," you're not entitled to charge the same prices. What they're not understanding is that in certain circumstances, we pay MORE for our supplies than wholesale. I for one wish Sam's would carry cake mixes, but I digress...
I've dealt with this before. And ultimately, it's up to you to decide if "getting your feet wet" in the wedding world is going to be worth taking this order or not.
The large cake in my gallery and the fondant groom's cake that went with it easily carried 220 servings. Now--I do "small" meaning like 20 servings--wedding cakes on a weekly basis. In fact, I do so many of them I don't even bother to post them. Believe me--I was really excited and happy to have a big wedding to do. But at 1:00 am, with my feet swollen and my head tired, I was thinking, "Man, I should have charged $1000 for all this dang'd cake! GAH!"
Just be clear with yourself if and/or when you take this project on. Even the sweetest of brides (I've been lucky) can be quite a hand full! There are phone calls, trips and supplies you'll spend money on that you probably haven't even thought about, lol!
I'm sure what ever you do for them it will be wonderful! Best of luck to you and POST PICS!!
Your work is beautiful. Seriously--it is.
