Build a 2.4 m round plywood platform with 2 joining halves (Sydney)

Hi, I’m looking for a Sydney-based handyman or carpenter to build a round plywood platform for a wedding on 26 December 2026. * Size — 2.4 m in diameter and 200 mm high. * Material — Plywood with sturdy supports underneath and a smooth, enclosed curved edge. * Design — Two separate halves for easy transport. The halves must connect securely so they can’t shift apart during use, and the top must sit flush across the join. Please include the hardware needed to connect them. The platform will be used outdoors and needs to safely support two adults, whether seated or standing, and stay stable as they step on and off. I’ve attached a diagram showing the size and layout. Please let me know how you’d support the platform underneath and how you’d connect the two halves. I’m happy to discuss pickup or delivery within Sydney.
