add some landscaping to existing 3d site model (architectural landscaping)

I need some landscaping design to be added to my site model. I will advice the areas for the greenery and the basic plants/trees required. The rest the designer will propose on beautifying the site. Main intention is to make my building site like a botanic garden, where visitors drive into the site and feel very much like in a garden. To include a nice simple water feature near the entrance close to the building. Other areas need not propose as the model is still ongoing...show me your portfolio of architectural landscaping designs. Once the freelancer is selected, will provide the necessary files to work on. Dateline is within 48 hrs...you need not do a high res full render, just a small preview for me to approve and I will do the final render. My 3d file is in Vray renderer.
