Bulk URL submission script.

I am needing a script, hopefully already written that I can integrate into my site. I am needing a script that can Submit a URL to as many search engine as possible. An affiliate URL or a shortened URL. A script that a user can submit one URL, and one version that will allow me to submit a List of URLS from a text file. I am open to all ideas relating to promoting a list of urls. Anything that can get traffic to the urls. Thanks,
