I have been stalling on setting up a business website for years. I've started some initial research, but the domain link cost has also been an issue for me...and some of my research has mentioned having more than one domain name link to the website (in my case it would be a personal name and a business name). I do know that a lot of people find my business through Facebook and Google because I have a facebook page and I pinned my business address on Google Maps.
It might just add to your confusion, but on Eventbrite there are many free website building workshops/webinars that you can sign up for. Often they are linked to specific website builders (sponsored??), but if you are considering a change from Wix, learning about other sites, such as Wordpress or Squarespace, might be helpful for you.
