Hi there,
I currently work as a full-time web developer but am seeking to build up a freelance portfolio with projects like these. I have daily experience in taking ideas and building them out into fully functional sites. Typically I build in Ruby web apps and always with a HTML/CSS top layer. It sounds like you're looking for a WordPress or static site?
If you are looking for a WordPress site, I recently took a Masters-level course at Harvard Extension in Content Management Systems, which included heavy instruction in WordPress, and am adept in its usage.
If not, a plain HTML/CSS site, especially if built with something like a Bootstrap framework, shouldn't take much time at all. Either way, I hope to hear from you and learn more about what you're looking for!
Best,
Rachael
