I basically only design stand alone html sites without a back end database. I've tried both Joomla (see http://htl.org.au/ - a Joomla site I designed recently) and Wordpress (although I hate the latter and it is a target for hackers as so many web sites are wordpress based) but nicepage allows me to design sites the way I did in NoF. The available templates and blocks are modern, web 3.0 and fully responsive. SEO is as easy as it was in NoF and there is a fairly good support forum. It suits me because I can think and design visually and so far I haven't run into any snafu's that I did when learning the other mentioned apps (including Mobirise and Artisteer). Download the demo and play with it for an afternoon. I think it will meet your needs from what you've said and it has a shorter learning curve than the others. I also use Mobirise but don't find it as intuitive or easy as nicepage.
