美国采购需求：足球场、足球场、足球场、足球场、足球场、球门柱

I am interested in sourcing a shot clock, scoreboard, and sensor designed to accurately record basketball shots. The display needs to be clearly visible from a distance of 50 feet, so I'm looking for options that utilize 5-6” LED technology. Additionally, this system will be mounted on a basketball backboard, which should measure either 36” or 44”. Could you let me know if you can manufacture or supply something along these lines? It would be great if you could provide details on the specifications and pricing for delivery to Maine, USA. Looking forward to your reply!
