Need a few changes making to my site

Hello, One of my websites 2-3 years ago crashed and I never bothered to get it back online. A few weeks back I realised all the old pages were archived so I saved them to my PC and reuploaded. The problem is, however, that I have ~220 HTML pages that all need updating. I need to remove the [login to view URL] links and links to a few redundant pages on the site. The changes I want to make are very simple - I just don't want to hand edit 220 separate pages. There are two ways to do this: create some sort of template that allows editing of all the pages, or make the changes by hand to every page. I'm not an expert in this area so I don't know what'll be most cost and time effective. Look forward to discussing the site with you! Tom.
