White Hat SEO possibly Grey but no Black Hat needed

I run a tutoring company based in Chicago, IL, USA. I will not list my website here for privacy purposes. Most (if not all) of my target keywords for my website are ranked in the top 50, with some of them being in the top 20-30. I need someone who will propel my target keywords into the top 10 (and preferably the top 5) as well as a GMB boost. I know that I am very close to achieving that result, but I need someone who will take me to the mountain top.  Need White Hat SEO possibly grey but no black hat!  Especially no automation!

Here is the list of my keywords with search volume:
