Event Schedule Management Solution

I need a reliable system that keeps every part of my event schedule in sync without constant manual oversight. The core of the job is to set up (or build, if that proves quicker) an event-focused calendar that:

• sends automated reminders to attendees and staff by email and, ideally, SMS
• lets me create and reuse customizable templates for different kinds of events (workshops, multi-day conferences, single-day launches, etc.)
• syncs flawlessly with the calendars most people already use—Google Calendar, Outlook, and iCal are the priority

My expectation is a smooth, user-friendly interface where I can enter or import the event details once and trust the system to handle the rest. If you have past work showing similar scheduling or calendar-integration projects, please share links or brief descriptions so I can gauge fit quickly.

Deliverables
1. Fully functioning event schedule manager with the three features above activated and tested
2. Brief user guide or loom-style walkthrough that shows me how to add events, apply a template, and confirm reminders are firing
3. Source files or access credentials, handed over on completion

Acceptance criteria
• A test event populates, triggers reminders at the set intervals, and appears correctly in Google Calendar, Outlook, and iCal
• Template edits save and can be reapplied without error
• No visible errors or missing data during import/export

I’m open to the tech stack—whether you prefer a no-code platform like Airtable/Zapier or a custom web app—so long as the final result is stable and easy to manage on my end.
