OK..You can freeze cupcakes, undecorated for several weeks, if you freeze them in a single layer, then store as airtight as possible. I use bins in my freezer I find at stores like Target and Walmat. They are plastic with seal tight lids, I think they are called something like "store and lock". The lid has a plastic ring around it, with a "flap" on each of the four sides that lock into place. I do have trouble finding big ones. You can freeze them for several hours or over night uncovered, then stack them, with parchment inbetween, in the boxes. I think you have plenty of ideas for cake stands. As for a red velvet cupcakes, the one in "The Cake Doctor Cupcakes" is a favorite of mine. I have changed the basic mix around for use in many other cakes. My clients think they are the moistest cupcakes they've had, and with all the add ins no one suspects it starts with a mix as a base. Transportation is always a problem with cupcakes. If you have the time and budget, there is a box company called "Big River Boxes" (google them). The sell boxes and cupcake inserts that I use. They are the only company that I have found (although I admit after I found them, I loved them so much I quit looking!) that have the inserts. They are not too expensive, although if this is a one time thing for you, the additional $100 or so (boxes+inserts) would probably not be cost effective. The shipping is free and fast. I hope that helps you some!!
