3 x holiday e-card options for a corporate audience

I need a set of holiday e-card options for an international audience. This will mean:
- Sourcing royalty free images appropriate for holiday cards, with a theme of nature (eg winter vegetation/birds/animals etc) - I can supply examples of the style I'm looking for;
- Creating three options: (1) a Christmassy personal feel (although not with Christian imagery or wording as we have an international audience); (2) a more "corporate" feel for those who want a more business like flavour (possibly incorporating a globe either as a holiday decoration etc or in another way and using dark blue, which is our corporate colour); and (3) a neutral third option.
- A splash of red would be most welcome and we have a "holiday" logo to include.
- wording to be "Happy Holidays" or "Season's Greetings" though we will also need the same greeting available in Spanish ("Felices Fiestas")
- I have left this super late so speed is of the essence - I'd like some options over the next two days if possible.

Ideally we would like the artwork to be delivered as a layered Photoshop file.
