Blender3D job: model pic from 2D image

I would like to generate a 3D image using Blender3D. Please see the '2D_image' and '2D_image_90-degree-rotation' to see what the project involves. It involves making four large oval shapes coming together to form a central hole. These four ovals are surrounded by a layer of another shape: small circle with two curved lines coming from it. The image is actually of something called a lipid bilayer or membrane. You can google those terms to see many examples of what the end product would look like; I've attached one called CGI_image.jpg. The project is really quite simple: make two shapes, arrange copies of them and then render the scene (or I can do the rendering). Looking forward to your bid.
