Bitcoin Giveaway Website - repost

I'm creating a one page website. I will need to have full control over the content on the website so that I can add or remove something from the page. On the page, I will require the centre of the page to have a place for me to put a company logo (or image). When someone clicks on the logo, it would redirect them to a URL back link. (I need to be able to have access to change the logo and URL myself). Beneath it, I'd like to be able to edit a text box by logging into the admin page. I'd also like to enable a comments box below the centre logo and text box. The comments section should have a username and comments box. I'd like to also have access to being able to delete these comments entirely every few days. (Not individually, but all comments at once). Once I delete the comments, then new comments can be made. That's all I need. Not more. Looking for a nice layout though. Perhaps a light grey background and some nice fonts. Thanks
