My answer is probably boring, but it works, and I had fun with my own. Just set up Wordpress. At this point, you can find templates for any site design imaginable, and there are a million plugins for it. It's an all-around solid platform, that has mountains of documentation. Wordpress was made for blogging, can't go wrong there, but I've used it for all kinds of stuff, including ecommerce. It's simple and effective enough that I have a hard time going any other direction.
I used to host Wordpress sites on a home LAMP server; it was a fun project that didn't cause a bunch of headaches, mainly because of the amount of available documentation. Search "wordpress self-host" and you'll find a whole lot of information.
Good luck with whatever you decide on!

Careful with their hardware; it's no longer the company that built the name.
