AHow much shouls I charge for a cake like this. They need it to serve 8-10 people.

Ashould

i'd recommend that you do a search ^^^ in the search field for pricing information--there's a ton of it already posted.

a 10 serving cake is so very small -- i'd pipe a flat picture of a football on a (piped) grass topped cake--it's not really big enough for much more than that
