Great idea, Nikilette, though unfortunately LinkedIn does not provide an easy way to import recommendations from other services.
Based on my research, the best option would be to use the Box.net application for LinkedIn and upload all of your recommendations in a document. More information on that approach is here: http://www.linkedin.com/answers/using-linkedIn/ULI/759443-24583343
Let me know if you try this and, if so, how it works.
