Want to build an Actuator - Regarding Robotics and Automation -- 2

I am looking for a qualified freelancer to develop an actuator suitable for both indoor and outdoor environments. The actuator must be cost effective and capable of operating without needing human interference. I already have an implementation plan in mind, so I will require someone with the necessary technical know-how to get the job done. If you think you are up to the task then please don't hesitate to contact me. I look forward to discussing my requirements and possible solutions with you further. Thank you!
