Building a small business website?

I’m the most tech-savvy person at my job. That’s hilariously sad, but true. My level of understanding is, like, I can use the internet for regular everyday things. I have an extremely limited knowledge of HTML, the way someone might know a few basic phrases to get around in another language.

I’d like to build a small website that acts as an extension of the store’s business card. Maybe if I get ambitious, it would be nice to add a staff blog to that a little later. Where should I begin?
