A bottle of water with gradient transparency

Hi Please see this image: [login to view URL] It's a x-ray scan of two water bottles, the right bottle is empty and the left one is full of water. We need to model the left one. As you can see x-ray beams couldn't reach the center of water. Water is a condense material and beams will damp in the middle of bottle. So the center is darker and we see a gradient color. The bright orange colors are transparent and if we have an object behind bottle we should be able to see it. From shell to the center of water should be a smooth gradient. Delivery: A file in FBX format or other 3D formats. **IMPORTANT: BID WITH SCREENSHOT**: With your bid please send me an screenshot image of something like final model that shows you are able to do this project. I will not accept bids without screenshot. I know this is not a normal 3D design as 3D softwares are working with surface of objects. But we have many objects like that to model, so if you are able to build it, there are more and we can continue. Thanks
