Do some 3D Modelling -- 2

I have a project that I need 3D models done of fitness equipment. the equipment is what is known as Crossfit Rigs. see this link with our current models that all need to be updated to higher quality renders and adjustments made for our new model [login to view URL] [login to view URL] I need each version to be made from 10 cells down to one cell. I want high quality renders that need to look real. I will provide all specs for all components. Also our new website will have the capability to change colours by selecting the colours required for different components like on this site [login to view URL] I don't require the multiple colours in this round of the rigs but I want it so it is an easy transition to make the coloured versions.
