I like how the original poster has discarded all of the helpful suggestions as 'unnecessary'. You'll just get told the same thing by the person you hired if they're professional and serious about what they do. If not, run a mile or you'll end up with a terrible website! Seriously, take on some of the suggestions here or else you'll regret it.
You really don't want a website like that. The moving items will distract your readers from finishing reading the comic
You should look into WordPress for publishing comics. There's even some free web comic themes around for it. They make publishing comics really easy (the only hard part is drawing). The free comic book themes I know even have some customization options.
My advice is to take the WordPress.org package with your own paid hosting. WordPress.com has free hosting, but you can't use the webcomic theme.
Hello, I know someone who has a content management system. It's a website system where you can make anything with very easy. For example, you can create an album in just a few seconds and fill it with pictures. Or just a normal page.
Some examples: [link], [link], [link] It's very nice to work with. The layout is a bit difficult, but you can get help with that. Should I contact this person?
That sort of thing it totally doable keeping in mind the loading aspect, if the developer couldn't/didn't do it correctly doesn't mean the concept/idea itself is rubbish, like others have pointed. Email me to discuss on the aspects of concern in the design and other things. Meanwhile have a look at my portfolio.
I would like to say that the Boris Vian site you linked to is HORRIBLE. From the point of view of the web user it made my eyes hurt (I couldn't focus on anything)...it's too busy, hard to work out and, in order to navigate to any information, you have to click three times and wait for a load screen...arrrrrgh!!!
Really, you are unlikely to get many 'casual' web visitors to stay on your site if you copy this design format...they will click on it, see it and leave. No matter how well it's done.
I build my own websites (and for others) but I'd refuse to build this on the above grounds - take my advice and don't do it
