Need Squirrels Removed From Roof/Attic And Prevented From Re-Entry

Hello, I need Squirrels removed from roof entry into attic and the entry point sealed to prevent re-entry. I posted a few photos of the small opennings I believe one or both the squirrels are entering from. These are close to the edge of the roof, in the back yard of house and is not too high up for accessing. You must have prior experience doing this kind of job.
