I need a couple of simple illustrations for my business Christmas card

Hi, I've recently started my own copywriting business and am looking to create three different Christmas card designs (as jpegs) I can then upload to Moo to create my own cards. One is very simple indeed - just type, saved as an image; one is a simple line drawing of a Christmas tree (all black and white bar a single splash of colour), and one is a cartoon of a lion, but still mostly B&W with splashes of colour.

My website's not live yet but I'd want the splashes of colour to reflect the purple on the temporary site: http://kathrynsavillereilly.wix.com/copy-by-claire

Ideally I'd like this within the next week
