Easy Web Designing Services

[rawfuls]

Not sure if many will know what I'm looking for..

But, I want something similar to squarespace.
Something easy, simple, but can be made complex if wanted.
But MUST be free and MUST be able to be directed to by a custom domain.
*(we bought a domain, so if someone types our domain into a browser, it will take them to the website..)*

It's going to be kind of just an informative website, not one that needs to be flashy, doesn't need to incorporate forums, kind of like a news updating thing, but not a blog.

Looked into an alternative like drupalgardens.com, but the free service does not allow the custom domain directing part.

Normally, I would shell out some money for a good service like drupal or squarespace, but this is for a nonprofit organiaton/club at my school, and we raise money, and also try to help the autistic kids doing minor things, etc etc.

So obviously, we don't have the money to make the website..
Something simple, easy, and free, would be glorious.

If anyone has any ideas, that'd be great!

Thanks fellas!
