Homepage image concept and design

My development site

http://easyremote.co.uk/YEP/backup/index.php

As you can see, I have all my products and pages in place, what I need is an image for the homepage. Something attractive and professional.

My creative side is lacking so I'm looking for someone who has a creative side, who can then turn their idea into an image.

What I'm thinking is an image that is divided horizontally into three parts. Each section will link to one of the three product categories (Work, Sleeping, Leisure).

You then use your magic to make the three parts come together as one masterpiece. You can use whatever you think will work best within the images, take inspiration from the products on those pages or whatever suits the site best.

Challengers; I don't have many products on the site yet, and most products are repeated in each category, so you'll need to bear this in mind.

I want the image to be timeless, so no "50% off this week" or anything that means the image has to be changed any time soon. I don't plan on adding any additional categories at the moment so spend time focusing on the three horizontal images as described to make up the full page.

Although I talk about 3 images, they will appear as a larger single image on the homepage, I only mention three so I can hyperlink each one to a product category, if can think of a better way of doing this I'm all ears.

Other Information:
Site is created within Magento, so any experience working with this package may be on some advantage. I'm using the modern theme.

Once completed, if it's in illustrator or whatever, I'd appreciate the raw format of the file as well as a web friendly image. So for example if it's created within illustrator, send me the .ai format without converting the text to paths (i'll find the font) so I can change bits and pieces on demand. Also send a nice friendly .gif or .jpg, whatever you think is best for the image(s) on the front page.

Response Request:
I'd appreciate if you gave a brief summary of what you believe I've asked for so I can confirm you've understood the job and not just sent a generic response.

I welcome clarification questions as I'm sure I've missed out some important details.

Thanks
Ryan
