I have not doubt that you can duplicate or comethisclose to replicating it. But I also agree, it's not that you can't do it, it is the amount of time and maybe even extra help that you are going to have to get to help you with it or handing you the vodka shots
. In all seriousness, though, should you decide to do this cake, I would definitely not charge less than $6,000 to $7,000; hell, if MB starts at $10,000, then I really feel (in all honesty) that you should go with that price - hell, the bride wants a duplicate of that exact cake, then you have to pay the exact duplicate of what the original costs! Also, if this bride can afford that kind of price, please make sure to get 1/2 of the total cost of the cake at booking! Good luck and keep us posted!
