One of the first things that you need when you have a small business is an online presence.
First, you need to find a domain name that nobody else has. Some examples of a domain name is: google.com, amazon.com, or anything .com, .net, .gov, .io... etc
After you get a domain name, you need to buy hosting to place the content of your website that will be displayed when people visit your website. This is where you design the look, feel and content. This is also where it could get tricky.
Most people use Wordpress, which can be a little complicated to set up if you do not have any experience with a c-panel. But, if you are comfortable with the cpanel, this link is a great hosting site that I've been using for years.
If you need to drag n drop, go with wix, weebly, square or any of those websites.
