Auto download from ftp upload to http script.

I want a script that monitors an FTP for new folders, and as soon as one is present (and complete) it will download automatically. After the download is complete, it will be necessary to delete 2 files from the complete download. After this, the file needs to be RAR'd with the filename of the folder just downloaded, then uploaded to [login to view URL], before being posted onto a forum with the rapidshare link to the upload. The server it will be running on is Windows Server 2003 Intel Xeon CPU E5506 @ 2.13GHz 30gb hdd 768mb RAM. For more info please contact me.
