Website Upgrade Assistance Needed

I am seeking a skilled freelancer to assist with upgrading my website. The project involves updating the current version to ensure it is secure and functions smoothly. The ideal candidate should have experience with web development and design, particularly with Wix. Attention to detail and the ability to troubleshoot issues are essential. If you have a strong portfolio and can deliver quality work, I would love to hear from you. I have a website already on Wix but I need to upgrade it, make it look more simple yet professional yet luxury when businesses view it. I want to change my color scheme to emerald green, gold, off white or cream and black. I offer courses to individuals and businesses I need my website to reflect that. I sell books and digital downloads, I need those to be added to the website. also if there is a way to funnel and upsell example they purchase a book or viewing one of my books but you upsell to join my monthly Connected Culture membership on the Skool platform.
