58729 Website Monitoring

I need a basic application for http only. It will have multiple accounts, each one having just one URL that is monitored every 60 minutes (variable in database per account), 24x7. If a failure is recognised then it is tested twice again each minute afterwards, and then on confirmation of failure an email is sent to an account specific address. When the site comes up an email is sent as well. Template will be provided, however we want reporting per account showing last 24 hours, last 10 days and last 2 months. Data is overwritten after 2 months. Will also have some basic bar charts. This is to be plugged into another product so we just need a log in page for the users. URL, email address, login and password will be passed from the main site to the database that you create. This has already been done many times before and with more features so let me know what you already have as we may like some of the extra stuff you offer (like SMS notification etc).
