Large Backdrop Artwork URGENT

I am looking for someone to draw, illustrate or graphically design x2 themed backdrops. They will need to have a final resolution that can be produced at 3x4m (3000x4000mm). The two themes will be a Broadway street scheme and a quiz type backdrop (who wants to be a millionaire) theme.
Please upload me suitable previous examples of work or better still a sketch of each to give me some idea of your standard of work.
These are needed to be more stylish and modern rather than cartoony and colourful.
This is an urgent job so the selected candidate would have to produce some finished visuals, not high res within a few days please.
