Do some 3D Modelling -- 2

We have some 3d models and textures. We require help on UV unwrapping them and mounting different textures on the [login to view URL] texture mapping is to be done from Vray. The output expected is a realistic texturing. Every model on an average would have to mapped to 6-8 textures. Appreciate quotes in comments as a per model basis. Total size of the project is 500 models. Want to split it into 5 of 100 each to gain on speed. 3 weeks to completion. Project would be awarded on 18th April 2014. Expected to be completed by 9th May 2015
