Bulk semi-premium iphone imei unlock needed


I’m looking to unlock around 1,000 IMEI/DAILY from AT&T "IN-CONTRACT" phones. I’m looking for a price of $ .25/IMEI. Can anybod help? It includes iPhone 4,5,6,6S but they are mostly IN-CONTRACT devices. Please PM me your best price as soon as possible. This is time sensitive and need to get this moving as soon as possible. Looking primarily for US based unlock service provider.
