Hi,
Different websites show different prices for website domain and hosting. You can compare the prices on different websites and purchase the cheapest one. I found Hostinger cheaper than GoDaddy and also along with website hosting, Hostinger will provide you with Wordpress website themes and custom Email ID.
Let me explain some technical terms
Free Wix websites provide subdomains like abc.wixsites.com and wixsites.com is a domain.
Wordpress is a website builder tool where you can find pre-made website themes catering your business needs.
Also, you can hire website development services if you are not sure how to go with this by yourself. They can also guide you to suitable solutions for your website.
