Developer needed to support with website HTML migration and updates

We are taking ownership of our site code from our current agency. We need help with the migration and also making some content updates. The site files are in a ZIP folder which containt all pages, images, stylesheets, scripts, favicon, robots.txt, sitemap.xml and llms.text. Here are the instructions from them we need help with: 1) Your website files Download the complete site here (one click, ~2 GB): This is a full, deploy-ready copy of the live site — all 23 pages, images, stylesheets, scripts, favicon, robots.txt, sitemap.xml, and llms.txt. 2) How to put it on your own hosting (WE ALREADY HAVE AN ACCOUNT) You can use GoDaddy or any host you prefer. The steps are the same everywhere: Get a hosting account. GoDaddy's basic Web Hosting plan (~$12/mo) is plenty. During signup, choose the plan that includes cPanel + FTP access. Download the zip from the link above to your computer and unzip it. You'll get a folder with all the site files inside. Connect by FTP. Your host will give you FTP credentials (host/server, username, password, port 21). Use a free FTP client like FileZilla to connect. Upload the files. Open the public_html folder on the host and upload the contents of the unzipped folder into it (the HTML files and the images/css folders — not the outer folder itself). Many hosts also let you upload the zip directly in cPanel's File Manager and "Extract" it there, which is faster. Point your domain (DNS). In your domain registrar, update the nameservers (or the A record) to the ones your new host gives you. Once that propagates (usually a few hours, up to 24), apexpostureandsport.com will load from your new host. 3) Editing the site going forward The site is clean hand-coded HTML/CSS — no WordPress dashboard, which is what keeps it fast. To make changes, you (or whoever takes over) can open the files in a free code editor like Visual Studio Code, edit the text/images, save, and re-upload the changed file by FTP. Anyone comfortable with basic HTML can update copy, swap images, or adjust the scheduler and call-to-action buttons. 4) Your CRM, phone numbers, and conversation history (GoHighLevel) Your contacts, scheduler, tracking phone numbers, conversation/text history, and automations live in GoHighLevel. To keep all of it, set up your own account. I will also eject the account ownership to you directly which will give you a second link to sign up. Once you're set up, your sub-account transfers to you with everything intact. If the account isn't claimed, that data is eventually deleted — so do this before June 12.
