Create a one-page bootstrap web-page plus make a multip-step input lightbox/greybox

I need a one-page bootstrap sales page that can be developed directly on the domain and web-hosting I already have. The style can be similar to e.g. [login to view URL] but I have smaller images available, so no full page-spreads is available now, however, the whole product we want to sell is the one image called [login to view URL], and it reduces the electric bill and gives a better electric quality and ultimately a better environment, so if you suggest some kind of stock phot that will just be for a first background, that would be fine. You don't need to make the configurator itself, but ON the page, you need to leave room for a kind of configurator-input series of questions that could appear inside the page itself. Please suggest the look of it, but you don't need to program anything particular, but just make sure that the page is shown using one include-file for everything ABOVE the start of this series of input questions and one include-file for everything UNDERNEATH it such that if we use any number of steps (4 or 7 different input-boxes e.g.) actually doesn't make a difference and we can just send people from the /[login to view URL] page to the [login to view URL], [login to view URL] etc pages. The intention with these input boxes is to be able to do a conifigurator where the visitor will be able to answer input, radio-style and checkbox-style questions as to their current situation so we can propose a solution. You can see an example on [login to view URL] just underneath the fold, although there I think it's implemented in an iframe which likely won't make it work very well on mobile phones. You will get a series of images that we have as well as logo etc. The sales text will roughly follow the content of a powerpoint we have, however it is in Swedish so you basically just need to copy and paste from that.
