Design Wordpress

I am looking for someone with portfolio to make some design on my Wordpress site [login to view URL] (still under construction). I don't need a new theme but you can design on the current one. All I need is to add some look-real nature elements surround the content, something like [login to view URL] and 84colors.com. The position should be static, like the 2 example sites mentioned. A problem is that my site has a much longer content, and if you click "Case Studies" at the bottom it will extend even longer, so I am not too sure what to decorate with those space, maybe just repeated sand background, or little grass, or something etc. Another question: If you look at [login to view URL], the nature elements like leaves and squirrel are actually moving a little too. Let me know if you can make this, or just non-moving. The 2 example sites are done well with the feeling that it is not just a background, but actually "surrounded" by those nature elements. That is the feeling I wish to create too. Deadline is 10 days upon hiring. The earlier the better. Thank you :) Best Regards, Terence Lim
