Purchase of iPads

Harlow College requires 1,800 Apple iPad 32GB Education model, we are happy with either colour or a split of 50/50. These iPads need to be brand new/sealed and all devices will need to be uploaded to the Apple DEP for us to use with our JAMF MDM. I believe Apple also offer Apple Professional Learning days as part of the education purchasing offer, can you confirm how many days of training we would receive when ordering 1,800 iPads. We would require delivery to be ASAP after the 1st August 2019. We do not require any professional services as far as setup, nor help with deployment or insurance. Financing of the ipads needs to be flexible and possibly multiple options.
