Ping Pong Soccer Table

Hi there. I am seeking a professional to help design a modular, outdoor ping pong soccer table. The dimensions should be 9' L x 5' W x 2.8' H. The structure should use HDPE for the top surface and lightweight and robust material for the legs and frames. I need support to design the 3D model and the 2D drawings. The intention is to build a modular table that is easy to assemble and disassemble. I am unsure about the budget yet, so I am open to different price ranges. If you have experience working with steel structures and HDPE that match my requirements, don't hesitate to contact me to discuss further details about this project. I will attach some pictures to get some ideas on the design. The structure is not that sturdy, maybe because it is missing trusses, so please, feel free to suggest any alterations.
