websites and IT - repost 2

HI, We are looking to embed a email that would be sent to a mailing list everytime we put a news item on our website or send a newsletter to our mailing list. Currently we intend (our website is not live yet, see this link for the work in progress ([login to view URL] ) that we'll publish certain announcements on our website and on the stock exchange (ASX). Most of these announcements that would be on our website we want to also email out to our mailing list. Not all announcements would be emailed automatically, we would want a "tick a box" approach when we enter the announcement as to which ones would be sent out as an email The email should be in good looking graphic format that includes the OncoSil Medical branding. We also want people to be able to subscribe to our mailing list on our OncoSil Medical website. We also want to insert email addresses to our mailing list, say as a excel spreadsheet (running in the background). If we meet people interested as investors or in the company and they give us their card we want to scan this in and then if possible automatically add them to the e-mail database to for our mailing list. We want a "unsubscribe" feature at the bottom of the email that refers back to the mailing list and marks as "do not send" for the individual, if people no longer want to receive our emails.
