footballs

will be selling footballs across the UK and am eventually looking to buy a large number of them from a manufacturer. I would like to buy a sample football first to view first hand and test before I choose the company.The balls would be used for training and match use. I have attached a football that includes the exact specifications (page 8 ‘futsal football test criteria’) for my balls.I have also attached a typical futsal ball. Can the ball be specific to my design ie size, weight, logo, material no. of panels?I am looking at buying around 100 football initially, if it is successful I will buy 200 footballs and keep increasing my stock due to supply and demand.
