Collector Website, plugin advice needed.

Good day,

I am setting up a WordPress website for my dad that is a die-cast toy car collector. I am not setting up a e-Commerce site where he will be selling his collection, but rather showing off his collection.

I have done a few basic WordPress sites before, but not so many that I am aware of all suitable plugins available to be used.

This is a budget project I am paying for out of my own pocket and as such I would like to keep the costs to a minimum, so please keep that in mind when responding.

I am looking to give him;

1. The ability to have some sort of gallery of his collection that can be filtered with various tags, such as, but not limited to; brand, size, manufacturer, etc.
2. Each item in the gallery should of course have its own page/informative section.
3. The ability to have several items group (possibly a link with a pre-defined filter in the url as per above). For example a Menu item that says My Collection -> Ford -> Mustang, which will then load his gallery with those filters)
4. A tutorial-like section. A place where he can show-case how has done some of his customization work.
5. Ease of use. I wont always be able to add filters, items, etc for him so something which will be fairly easy to teach him (as he says, he is a Dinosaur when in comes to technology).

In a nutshell, the vision he has for his site is simple. He wants to have a online gallery/collection area where he can show off his hobby as a collector and customization he has done on some of his items.

Regards,
Anton
