I did use Styled Components, but no css framework. The site was originally a 2-pager generated using Unicorn Platform. The client wanted me to Gatsby-fy that project and then expand upon it.
If you want to do it yourself without any coding, I'd recommend using https://unicornplatform.com
I created a bunch of landing pages for validation this way in 30 minutes.
If you prefer custom design and something that stands out, my DMs are open :)
We may adjust the prices but ideally we want people to accomplish their tasks, we don't want people to pay little no money and totally forget about it. We are also playing around the idea of paying back x percentage back to user on successfully accomplished tasks. https://unicornplatform.com/ here you go friend :)
If you're able to export the html / css /js files from your existing site, you can host it a number of places for free / almost free. Github pages has been suggested and is a good choice. Its a tiny bit technical to set up, but you can just follow a youtube vid.
Otherwise if you cant get the source code (which i suspect you wont be able to, having just looked at godaddys website builder), you'll probably need to rebuild it, either as it was or a new design. HTML5up.com has some great free temlplates that would probably work for you, or you could find a website builder that allows you to export the files, I think maybe Unicorn lets you do that.
