1 to 2 minute long 3D animated short film as per our script

We need an animated video that will be viewed by mature audiences (15 to 75 years of age). The style needs to be appealing to this age group and hence cannot be 'cartoonish'. The overall look and feel should be 'arty'. We prefer 3D over 2d because lighting is an important part of the story and we feel that 3d gives more control to create the right mood through lighting. But we are open to other techniques and 2.5 D if you have ideas for an artistic style instead of realism. Need the job done within a week of awarding the work. But this deadline can be extended if needed by mutual consultation. Final render of the animated short film would be in HD 720p Duration of the animated short would be around 1 to 2 minutes. The work includes sound design too. This is a "Work for Hire" contract and all rights will belong to the producers. Story is attached as a file attachment here.
