3D Product Rendering

We are in need of a freelancer who can do some realistic 3d product rendering for us where you can make 3d model product packaging to make it look realistic.
We basically are looking for someone who can create realistic render images of our product bottle. It needs to look a lot more realistic as it has proper shadow and lighting and so looks like a real bottle - and then we just swap out the label.
Please send your portfolio and sample work.
