Don't do it.
Get a host with WordPress (or joomla or another similar content management system) on it. Even if you have a bit of existing content already, it'll take you less time overall to put the existing content into a content management system (CMS) than to update html pages on a regular basis.
Once you have the site in wordpress or joomla, you can do the sort of basic editing that you want to do just on the website itself. Only a sucker makes a website without a CMS nowadays, writing HTML is slower, more prone to errors and inconsistencies, and generally makes something that doesn't look as good either. Updating my old html site took usually an hour, nowadays with wordpress I find an update takes about 15 minutes at most.
