Illustration for website 300dpi

In a few weeks we're launching a web selling a small selection of cult beauty products and I need a visual to accompany the launch. I want to do a "flash launch" where the shop is only open for a few hours and it has special launch prices for those few hours.

I'd like to use a really cool illustration (sleek and trendy but urban and comic-like) with a theme maybe along these lines http://www.shutterstock.com/cat.mhtml?lang=en&search_source=search_form&version=llv1&anyorall=all&safesearch=1&searchterm=sprint+in+heels&search_group=&orient=&search_cat=&searchtermx=&photographer_name=&people_gender=&people_age=&people_ethnicity=&people_number=&commercial_ok=&color=&show_color_wheel=1#id=68189926&src=646330d97015560d9748855d7934f278-1-11
