E-Scooter Swing Arm Design

I'm seeking a skilled designer to help me redesign the swing arms of my escooter which I have already done measurements and drawings of. The swing arms are for a Kaabo Mantis king gt and the intention is to produce a file that I can get professionally CNC'ed and installed to allow bigger wheels/motors. Key Requirements: - Extend swing arm length beyond the lower shock mount by 13mm. - Lower the shock mount by about 7mm on its current axis - increase left/right Swingarm spacing by 10mm - Primary material: Aluminium - Must be lightweight, durable, and cost-effective enough for practical use. Design does not have to be pretty - ill attach a photo of a basic design id be happy with.
