Modify some html pages

I have about 400 static HTML pages in which some code needs to be replaced dynamically. This can be done by a macro in a text editor probably but I don't have experience with that so better give this job to someone who can do this and can use some money. I will pay $25 maxiumum for this assuming it is a 10 minute job. I will put example of old and new cold below. old: <div id="player"> <script type="text/javascript"> var so = new SWFObject('[login to view URL]','mpl','960','559','9'); [login to view URL]('allowscriptaccess','always'); [login to view URL]('allowfullscreen','true'); [login to view URL]('flashvars','&file=videos/blah1-01.mp4&image=pics/blah1-01.jpg&author=blah&backcolor=FFBFEF&frontcolor=6B006B&lightcolor=000000&screencolor=FFBFEF'); [login to view URL]('player'); </script> </div> new: <video width="960" height="540" controls poster="pics/[login to view URL]"> <source src="videos/[login to view URL]" type="video/mp4"> Your browser does not support the video tag. </video>
