Improve my Squarespace website

My website is bland. It need to pop more. I have a new logo to incorporate into my website. I would also like to add a video on the homepage, as well as photos throughout the website to add color. The website needs to be very professional, nothing flashy.

I would like to add a "Client Portal" where clients can purchase services and take a diagnostic test.

I will have more photos to add later. Use placeholders for photos for now.

I would like to use Squarespace.
