An event calendar with subscriber for automatic/manual email reminder/campaign

Need a calendar build to be embedded to a current website. The application is similar to Google Calendar except with more flexibility for subscriber and event reminder management. Calendar: Grid appearance start w/ Sunday Embeddable & Re-sizeable USA holidays (nice, but optional) Manage Event: Create/Edit/Delete event Add/Delete subscribers to the event Email sent to subscribers has option to unsubscribe (automatic if possible – moved to “unsubscribed” group, but do not remove the subscriber from the database) Scheduled or manual email reminder (last minute cancel event notification) Manage Subscriber (Admin Only): Add/Edit/Delete Subscriber 2 Groups: Active, In-active (for unsubscribed or no email & minor) Only subscriber in the “Active” group will receive email reminder Visitor can subscribe to email reminder from the website (just first name, last name and email address + submit) Automatic birthday email on subscriber’s birthday (if any) Event Email Campaign: Add/Edit/Delete campaign to be used for either event reminder, birthday or cancellation notification (create one template that can be used multiple times) Subscriber Data: First Name Last Name Sex Birthday Phone Email Emergency Contact Emergency Phone Please feel free to ask for more details if necessary. Thank you.
