Set Up A Mail Merge Program

Hi, Thanks for your interest in the mail merge project. I am looking to have some sort of mail merge program set up or created. For our marketing department we send out a lot of e-mails. We use a generic word document template and copy and paste our research (website address, names and URLs) that is organized in an Excel spreadsheet into certain areas of the Word document. Once these website address, names and URLs are copied and pasted into the Word document, the Word document is ready to be e-mailed. This is very time-consuming. I have been told to get someone to create a mail merge system so the two documents can be merged together creating a message that can be copy and pasted into an e-mail. Right now I use office 2000 (Word and Excel) . Once the final system is set up to merge the documents I would need some sort of explanation on how to use the program either in text or better yet a short video. Any examples of your work would be greatly appreciated. Looking forward to your bid Any questions can you please let me know. Thanks Scott Gray
