Does anyone have a blanket contract that they use for their orders?  I know I need to have an attorney go over it as well, but a starting point would be great!

CakeBoss has a generic one I used as a starting point. http://cakeboss.com/contract.aspx

I also referenced a few others for guidance as they are posted for you to use. http://www.earlenescakes.com/wedcakeordfrm.htm and http://sweetartweddingcakes.com/Contract.html
