We want a Quotation for adobe premier pro. and adobe Photoshop for academic Institute

See my screenshot.  Call M-F during normal business hours. 

I would recommend to call Adobe sales, not to contact support! Or you can contact any of Adobe partners: https://adobedealreg.secure.force.com/PartnerSearch?lang=en

If you only want a single license, you can take the student/teacher all apps license 20$/month first year and 30$/month subsequent years. https://www.adobe.com/creativecloud/buy/students.html#

You realise it will be a subscription cost per student/user? You cannot buy outright, or per machine.

don't think this is the place for that.  might try adobe support.   or check with your academic institution.  they often have a way to do this...
