188621 html price changes

I have about 100 prices that need to be changed in an html menu. There are 5 menus each with about 30 prices on them. The page was designed by someone who loved dreamweaver and dhtml. It is very dense and will have to be hand done. I estimate it will take an hour for each page. I need it done this weekend. It will be about 5-6 hours worth of work. i don't need to be told about joomla or drupal. We are already converting the site. It's not done yet and the prices change at the end of the year. Should be easy money for someone.
