77823 Network Monitoring Script/Prog

We are looking for someone to make a script that will Monitor Web Servers such as how [login to view URL] does it. List of features: Allow user to signup and become a new member by choosing the amount of servers and services they want monitored. Allow user to edit their servers and services they want monitored, or cancel service. Be able to monitor services such as POP3, SMTP, WWW, SQL, FTP, etc. Be able to send notices to email, pager, phone, AIM, Yahoo, MSN when a service goes down and when a service goes back up. Be able to do charts with uptime and downtime percentages by day, month, year Be able to list the time and day a service or server was down, and be sorted by time, day, month, year. Have an admin interface for us to edit, delete, or add new users. We want pretty much a system as close to alertra as possible. We would rather it be in ASP, or ASP.NET using MS SQL, but we are not opposed to PHP and mySQL, so all scripting languages will be considered. Regards,
