Basic web design - Moving existing content

Moving existing content from a web-builder template, to create a new platform site design which allows me to FTP to the host server. Upload the New site to hosted domain. Ideally with CMS/administration ability. ## Deliverables The reason for moving the content format is that the hosting & domain have been provided by a 3rd party marketing company. The existing draft site which is mostly complete less some finishing & additional functionality, is not compatible for uploading to their server. As editing of the DNS settings is required, and I do not have access. The lack of admin access requires a base program such as dreamweaver or expressions is probably used (please advise if there is another way), so that the content can be uploaded via FTP to their server. As a novice, I would prefer to have this delivered rather than spend excessive time learning to? construct it myself with a inferior result. However, as I would like to edit regularly to update content, if you could advise if there is an option for this rather than my? having to use? these programs myself for updates.
