Banner design

I'd like to have a set of 4 banners designed. Designer will be provided with the theme, style and some artwork to be used. All banners have to look very professional. There will be some very detailed extracting from background needed, so bid only if You are really good in such work. Also they will require perfect web-optimizing work, making them as light as possible with no (or very little) quality loss. Do I have to add that All the 5+ line long comments will be ignored? Please, don't post long introductions to Your companies, just a link to Your banner design portfolio ONLY. Thank You.
