Need help assembling a greenhouse for garden project, Limerick

I'm setting up a small backyard greenhouse and need someone to assemble it from a kit. The frame is metal and the panels are polycarbonate. I’ll provide the manual and all components. Tasks include unpacking, arranging parts, following the instruction steps, securing the frame to the base, and ensuring the structure is level and stable. I prefer a tidy, weather-tight fit with no visible gaps. Experience with lightweight metal-framed greenhouses and basic tool handling (drill, screwdriver) is a plus. If possible, please explain any maintenance tips after assembly and confirm a rough waterproof seal check.
