Illustrator Needed for website

Hi, there. I am looking for an illustrator who can design and make a header image for my website and a couple of small 150x150 images from a photo image. I would like the header to look something like the http://vimeo.com/ footer image but with a playground or something similar (I am a web designer). I have loaded the type of illustration I want here: http://postimage.org/delete/4sdja7yva/.

Please could you send me your portfolio (if you have any) and I'll be in contact if you are needed :)

Kind regards, Alex
