Design 3D System Architecture Diagram

I would like to create a 3D business graphic that illustrates the various parts of a software system to make it easier for people to understand. I've included 2 examples - one that I have done in the past and one from a CPU vendor to show what I'm looking for. I'm hoping to find someone who has created these sorts of business 3D graphics before. I would like to have a draft and then allow for a couple of revisions before releasing the final milestone. I will allow for some artistic flexibility as I am looking for something cool. There are 3 files attached: 1. [login to view URL] - (this is the image I need drawn). This was done in PowerPoint but needs to be re-drawn in 3D. I would also like to separate the blocks and emphasize the Excel Medical Electronics part (by having more depth, etc.) The base color for that part should be #335f87. The other block colors can be other variants. They should all be 3 dimensional in appearance. 2. [login to view URL] is an example of a similar 3D graphic design 3. [login to view URL] - is an example of another on that I had done similar to what I'm hoping to achieve he - you can see it has a gray 3D background I'm not in a huge hurry but would like to have done within a week or so. I would like to have the ability to do a couple of revisions. I would prefer that the final diagram in in a vector format. I would prefer that someone has actually created business graphics before, but am open to whatever looks the best.
