Around ~$25 up to $70/ month but usually we pay annually since it's cheaper that way.

For one year of service it's ~$300 for the business plan, and $540 for the commerce plan since we run it through WordPress.

Eventually, we want to get to a point where the money is self-sufficient, and to hire a full-time (actual) Dev to make it running the page cheaper, and more efficient.

It was more of a hobby / passion project for the founder but he realized he needs to make it into a business of some sorts to keep the website up.
