If you have a product, business, or anything that could use a website, you should create your own site! I designed this website, I write all the blog posts, and create all the content for it. I use Wix, which has lots of free templates and things like that, although there are other companies you can use like Squarespace.
If you use Wix, which I used to make this website, just be warned that you have to pay for removing Wix ads and getting extra space. Technically you can create a website without paying anything, but it won't be as good as if you do spend some money on it. It can be a good investment, though, and as all entrepreneurs know, sometimes you have to spend money to earn it.
Creating a website is a great way to build a platform, especially if you have a mailing list or subscribe function like I have. That way you can have a collection of people who you can sell your product to and/or gain momentum for your company.
There is much more to learn about website building that I didn't have time to put here, so find out more if you're interested. Creating a website can be fun and educational, along with being great for your company.
