Are there any decent builder site with templates for a single page landing page? I used Instapage years ago but it got pricey and didn't seem as eye catching. Not sure if it's improved. Many people seem to use custom designed sites but that's rather pricey in the MVP idea testing phase. If someone has worked with a designer that's an audience and price fit for idea testing bootstrappers I'm open to that too.
I'm exploring creating an online course but initially my landing page will be gauging interest and building an audience with some checklists and light content.
