Execution documentation and design works

A compact electro-mechanical control unit needs to be developed: a motor-reducer for connecting to an existing mechanism of gears and rails, controlled by a key with smooth lighting activation. Switch key - the mechanism is such that the key is inserted into the lock - different key turns trigger different actions. 1 - turning on/off the lighting 2 - starting the mechanism for lifting the covers A motor needs to be selected that will ensure smooth movement of the gears: The entire structure is 60x60 cm, and a small motor needs to be attached, along with miniature lighting. Part of the space for this is ready - if it's not enough, we will come up with a solution based on your recommendations.

Need a professional engineer to calculate and design a modular trailer platform with a load capacity of 60 tons for a ready-made chassis. There are factory drawings. Changes need to be made.

It is necessary to integrate the NCS with the automatic launch system (catapult with a microcontroller) to transmit a signal to the microcontroller, which will initiate the operation of the catapult 500 meters away from it.

I am looking for a designer to prepare working drawings for exhibition stands. I need a person with experience working with composite materials, who understands their capabilities and limitations, and knows how to properly design parts for milling and production. The task is to create technical drawings, including visualizations: assemblies, sections, dimensions, fastenings, specifications, and other data necessary for the construction manufacturing. It is preferable that the candidate already has experience in exhibition stands, advertising, or decorative constructions and can offer practical, technological solutions for production. Here are some examples of the direction to move in: https://www.instagram.com/market_tablo https://www.instagram.com/crealle/ https://www.instagram.com/artefinal_brasil/ https://www.instagram.com/rahbardesign/ https://www.instagram.com/kiancogroup.cnc/ Attached photos also include samples. In the PDF - the design that needs to be tested currently. It is not guaranteed that this project will be confirmed and go into production, but I need to understand the designer's approach. In any case, the test will be paid. The working area of the milling machine is 2100*4100 (vacuum table and automatic tool change with 7 positions).

It is necessary to manufacture an aviation wing, I will provide the drawing or 3D model. I am considering materials such as: aluminum - extrusion or covered frame, carbon fiber composite materials your option.
