Groom's cake and possible wedding cake questions

Hi~

I am looking for a groom's cake either in the shape of Atlantis or The Great Pyramid or an acoustic guitar. I would like possible pricing for these...and something yummy. :)

I am also considering a wedding cake... not sure if it is too late to order?...for June 15, 2007.

We have about 240 people on our guest list. I would also like half one flavor and half another (a lot are allergic to chocolate...but for the rest of us...)

Thanks!
