Sketch drawing to CAD/.stl file

This is a test to determine if a CAD designer can replicate the texture of a hand-shaped climbing hold. The hold itself should be at least 30cm in length x 15cm in width x 7cm height. The most important features are the surface texture and features. We need to demonstrate texture that is as smooth as glass "slippery", gradually increasing to 60D sandpaper coarseness, in increments of "Slippery" like glass to, Extra-Fine (400, 300 grit) to, Fine (200, 100 grit) to, Medium (60 grit). Have the texture go from the right side "slippery" like glass to the left side medium 60 grit. We want to determine if this texture can be printed using the new HP Jet Fusion 3D 3200 printer. I large twinkie shaped design is perfect, some round edges and semi-rounded bottom edges, and flat underside. Make the design hollow inside, with a 3/8mm bolt hole in the center of the shape, from the "top".

childrens playground, just a simple base with 3 activities, a slide off of one side, a tunnel slide off the other, and a pole with two swings off the other.

I'm hoping this is a simple project. I have designed a headband (a variation of the coil soccer headband worn by the likes of David Beckham). This one is for the ladies. The coil (unlike the soccer headband) becomes larger at the crown of the head. I will produce it through 3D printing for myself and friends - so far this is just a personal project. Specs are in the attached jpg.

Design an electrical roller door. To allow various mounting positions and angles of motor. Neoprene or similar door material. Option to add window (clear and arc weld screen). Floor mountings to cater for uneven floor and also if door is mounted within two datums, flush outside or inside etc. Two switches top, two bottom for open and closed. Door roll housing should be able to mount flush front or flush back. If specifying a motor, this should be freely available in Europe and North America. Size approx 2500x2500mm. The winning design will become a prototype 3D animation would be beneficial. Cost is open to quotation.

We would like to create a 3D model for mohs surgery showing the way layers of skin are removed to track out roots of skin cancer Here is a diagram that reviews the technique. https://goo.gl/images/Ly85Qz These different pieces will have a counter sunk hole so we can glue a small neo magnet and hold it together Attached you'll find a basic idea of what we want here.
