Design a website header, Facebook cover and Twitter image

Hi,
I'm looking for a header design for my blog page, a cover photo for my Facebook page and an image for my Twitter profile.
I am a writer, and my website will be my online presence to I'd like it to reflect me and what I do.
I'd like the header to be 1024x204 pixels and the Facebook and Twitter images to be their standard sizes.
I like the idea of having a cartoon image, perhaps a little gothic, but I'll leave that to your imagination. My writing sometimes includes the paranormal so it might be nice to include a subtle hint of gothic elements, if that helps.
I'd also like an image of a black cat with white paws in there somewhere. If you check out my website at www.lizhurst.co.uk, you'll see why.
I'd like there to be a theme for all three images. Perhaps they'd be all the same, but adapted for their usage.
There's also the possibility of me having business cards printed in the future but that is not included at this time, just something to bear in mind when designing.
I'd like to see some drafts by Tuesday 12th February please.
Thank you for reading, and good luck.
