Its made with godaddy's WYSIWYG. I only know I tiny bit of HTML.
So you only know a "tiny bit of HTML" but you're insisting that you need to make a website from scratch
that looks 10+ years behind the times?
The time you waste trying to make a decent website with a WYSIWYG editor will be better spent
learning a few basics on wordpress.
The goal here is to get your offer up as quick as possible and to test it.
Not to learn how to make a crappy website from scratch.
Take up one of the offers you've gotten of setting up wordpress,
spend an hour clicking around the admin panel,
find a landing page template/ theme and
get something up.
The overall design will look much cleaner and you'll be able to accomplish your goal.
Which is to test your offer.
