Architectural rendering and shadow studies

We require two very high quality v-ray renderings completed of an apartment building - 8 storeys. The model is already complete - the 2 views are for daytime and dusk. Good reflections and lighting are important. Also some interior life might need to be added. Also, we require accurate shadow studies for the building and adjoining site, which we have also as a 3d model. We have one week to complete this work. Enclosed is a sample of the quality of visual that we wish to replicate for the renderings and the shadow studies.
