First you could break the inheritance from everyone, then assign your permissions. Also Deny permissions has higher priority than allow, so if you first set "View" deny to everyone role you will not be able to change this for one of your 75 roles until you break the inheritance from everyonerole.
All not special roles ( administrators and owner are special roles
) could inherit permissions from everyonerole as described in the previous post.
