Create a cheerful Christmas song with radio hit potential

We are looking for a singer/songwriter/composer/musician (yes, all rolled into one ;-)) to create a cheerful Christmas song for us with radio airplay potential in the holiday season. We are looking for a high quality production with original lyrics, vocals and music. So don't bid unless you can do it all and offer us a final mix including all elements. We have a preference for female vocals but if good quality we will accept male vocals as well. Don't ask me please "Ok what should the song be about?" or "What are the lyrics?" as the theme is Christmas and the rest is all up to you. 100% creative freedom :-)
