add CMS impress pages to our existing website

We have a website that currently uses word press we need to remove wordpress and add a cms such as impresspages that will allow some sort of drag and drop function when editing and allow us to add text or images as if we are typing direct onto the webpage so its easy to see exactly what we are doing and the page that we see in the editor is how the page will end up when the page is published if you think you can do this please contact me
