prototype a remote controlled robot

I am a senior executive with many interests and accomplishments. I have an idea for a new business and I need a prototype to test the market. There will be several stages to this project but I will only describe the first few here. The rest will depend on the success of these. I am expecting these stages to be very inexpensive since they appear to be larger versions of things I have already seen on Youtube. I will be happy as long as they work and look presentable. Please bid on Stage I as a project. The other stages will probably be hourly. Stage 1 Compose a Bill of Materials (BoM) with which to build a life size (1.8 meters) robot; for each item on the BoM, give a link that describes it and its price, delivered to you; the body should be full, from head to toe with arms and hands; the body should be detachable at the waist for transportation purposes; the body should be standing on a motorized platform (4 wheels); The motorized platform should be capable of supporting/pulling 100kg; The battery powering the motors should be rechargeable and be able to travel for 10 hrs. between charges; The arms should be capable of extending to the floor; the hands should be capable of grasping an object; power for the arms and hands should come from the same battery; all motors should be wirelessly controlled either through RF or cellular data (preferred); devices for remote control may be either joystick or touch screen. Stage 2 we will meet over ZOOM for you to explain any questions I have about the BoM; modifications might follow; once finalized, I will order and pay for all the BoM items to be delivered to you. Stage 3 you will build the device; you will demo the finished device over ZOOM. Stage 4 you will ship the finished product to me.
