Sketch out your website on paper - especially your navigation. Keep plenty of notebooks handy.
I usually sketch on paper or in LibreOffice Calc (I use it like a word processor because I can have many sheets available at once, visually, and I can link cells).
While I do not prefer them, without a lot of customization, use Joomla (my preference) to do a quick website. Joomla is very easy to use for prototyping. It does not have to be pretty, or even secure at this point.
Find a Joomla template (plenty of free ones out there - templatemonster.com, for example). Plenty of plugins to do what you want as well, many free.
You should get a bit of knowledge -- take the W3 tutorials on CSS, HTML, mySQL, javascript, jquery, etc. etc. Determine if you need a lot of interactivity, animation, etc.
Creating a website is not as easy as going to godaddy, bigcommerce, shopify, etc. and using their stuff. In fact, stay away from them. Developing a decent website is actually darned hard, and requires a lot of different things. Teams are nice to use, but not always available.
Later, when better flushed out, one can actually do the website (I prefer doing in pure PHP, CSS3, and HTML5 -- using as little jquery/javascript as possible).
