Help setting up my squarespace website and general technical assistance from time to time

I need a simple website to help clients and referrer's find me as a psychologist, as I am moving from contracting to my own practice. I have began setting up on Squarespace. I know what content I want and have a professional photographer to do images of me and once I have it the practice venue. I want to be able to add content (interest articles, blogs, links to you tube videos) later. I am in my 50's and time poor, so need someone familiar with the platform to help me with technical issues, formatting etc, so I don't waste time. My ideal help is bright and quick on the technical issues, able to communicate well and understand what I want quickly, willing to help me learn and patient with me. My ideal would be someone who can sit down with me in person or via screen share and talk me through tweeks I want to make to the site. Ideally I would like them to become a tech "go to" person who can help me trouble shoot these and future tech difficulties on a per hour basis. I am very flexible about hours, so consults don't need to be in business hours.

Once the website is up and running a second bit is helping me optimise for search engine hits.

I do not want on line booking, forms or anything complex, just funnelling referrals to my work mobile and e-mail. I offer a lot of bulk billed sessions as there is real client need and my goal is to keep my costs low.
Thanks
