Children website design with vector graphics

A website design is needed for 4-5 pages . The UI mockup will be given in a PDF sketch format. The website should retain the simplicity and ease of use of popular websites like stackoverflow or google products (docs, gmail etc.) but still have a colorful theme that can be appealing to children. All graphics shouldn't be raster looking but rather vector. For examples and details please contact me via PMB . Also if you do not have a portofolio with at least one website that can meet the upper characteristics (simplicity, vector graphics) please do not bid.
