Help Finish and Maintain My Squarespace Website

I recently launched a new consulting business and have a Squarespace website that is about 90% complete. I'm looking for someone to help with the final design, formatting, and mobile responsiveness so the site looks polished and consistent across desktop and mobile devices. Beyond the initial cleanup, I'd like to build a relationship with someone I can reach out to from time to time for website updates, new content, and occasional enhancements as the business grows. I'm looking for someone who is responsive, has a strong eye for design, and can make practical recommendations to improve the overall user experience.
