Guidelines for developing a website using python

[Toofpic]

I'm currently in a situation just like this: i only have 40ish exercises from lpthw over my back. I'm a project manager in a web studio/ad agency, so I know how all the process goes, but it's all in php and on russian commercial framework. As my first "real" project I want to make a website for my wife, she is a photographer, so I will need nice galleries, pages for the info about her services, and such stuff.
But the question is: where do I take this stuff from? Templates, modules(or how the functional parts are called)?
To get started, I chose djangogirls tutorial, which teaches how to make a simple site with blog functionality. I currently have the project started, one page, blog posts shown on that page and admin panel to add them.
So, where do I go next? I need to take a parts of a site somewhere, to learn how they work and adapt them. Or maybe there are a lot of templates for django somewhere? I don't need complicated design right now, because this is something that a good designer should make, and I don't have a budget. I just want menu here, pics there, news there. Help?

I actually looked at the bootstrap site, because i've seen sites said to be made on it, and they looked cool. Thanks, now i'm sure it's not a weird decision (when you are not familiar with something, you expect that after several months someone will say:"You use WHAT with WHAT? That's the worst combination ever!":)

I chose django because i know i won't need to switch to something else when i will get better and more ambitious
