Excel combine files plus

I have 7 separate Excel files.
Each Excel file has a list of names & phone numbers, with the same layout as shown.
I want all 7, combined into one file with the same layout.
I then want all numbers beginning with "952" & "951" deleted from the list.
I then want all remaining duplicate numbers deleted. There will be a lot.
Finally, I want all numbers in the order of the highest number at the top of the page.

At all times, the names and numbers must not be mixed up.

I will award this job to the freelancer who can complete the job the quickest and most accurately.

Thank you
