Update internal links in 200-300 sharepoint pages and docs

We have about 1200 wiki pages, documents, excel spreadsheets and other content types that have recently been migrated from one intranet site to another. About 25% of those pages and documents contain links to other pages and documents on the previous intranet. Each one of these 200-300 pages must be updated so that the links point to the equivalent document or page on the new intranet. Detailed instructions on how to do this will be provided. You need to be familiar with the "Manage Content and Structure" part of Sharepoint 2010. You need to be able to find the links, update them and test that they work. You need to be detail oriented and thorough. You need to have access to Word 2010, Excel 2010 and Powerpoint 2010. If you are not familiar with content management within Sharepoint, please do NOT bid. Sharepoint developers with no content management or data entry experience should NOT bid. This is NOT a sharepoint development project. (Unless you have a tool that can search and replace the back end links inside wiki pages) This work is ready to start straight away, and it would be great if it could be finished within a week.
