Vertical water tank with exclusive design in 3D

We are looking for designers who can make 3d models (in STL format) from 2D images. The images are furniture or jewelry. The models should be only the geometry shape (STL) . There is no need for texture, color or rendering. We would like to have at least 100 models per week.

Our mascot has lived his entire life as nothing more than a 2D image on a screen. It's very sad, and it's time that changed! We would like to render our buddy into 3D with the ability to print and assemble him with the new wave of MakerBot 2 3D printers. The output should be an SLA files we can slice and print. The final piece will be used as promotional material and/or just something around the office.

The spiral of learning (Kolb & Kolb) is a simple helix visualising the learner's progress. I need to visualise a more complex spiral. Turns on this helix are circular. Each turn represents an interaction between teacher and learner. This helix contains 1 grand turn. A grand turn contains at least 3 smaller turns. This creates a turn complex. Each turn achieves a small or large rise on the z axis depending on the diameter of the turns on the x and y axes. In elevation view the turn complex should have a stepped appearance due to the presence of the smaller turns, with the lowest steps at left and the highest at right. The idea to be communicated is that the larger turns contain at least 3-5 smaller turns. Each turn achieves a small increase in z-height as the learner exits the turn, like freeway traffic using a cloverleaf junction. Multiple interactive turns aggregate to a large gain in z-height. In the attached illustration, the largest loop should be understood as not a part of the visualisation. I would like to see two variations of the design: (1) smaller turns ranged on outside of grand turn diameter (2) smaller turns ranged on inside of grand turn diameter.

3D modeling of a J-shaped massage tool, much like a Theracane only smaller in dimensions. The tool should be modeled as close as possible to the attached images. The straight portion of the J-shape is approximately 10 inches long and 3/8in in diameter. The hook portion of the tool should form an approximately 180 degree arc and terminate in spherical end of 9/16in diameter. The handle, at the top of the J-shape, should be approximately 3/4in in diameter. The attached jpg images are of the actual tool that I would like modeled and should give you a good idea of it's dimensions. The png file should also provide a good reference. Thanks.

Design should be of a liver shell. It should be an anatomically accurate model that can be printed if needed to. The inside should be hallow and the liver should include a hole on top where the hyper-vein would normally be and a hole on bottom where the vein would leave. The liver shell should be a 2 piece design that can be clicked/ screwed together to symmetrically put together the 2 halves. http://www.exchange3d.com/3D-Model-of-Liver-Anatomy/prod_28235.html#preview A more simplified version of this will be perfect.
