Cron Jobs for timer functionality in Home automation system (Node.js)

Hi, I already have an app and server working, for a home automation solution. In the current version, the app is able to send the request to the server for turning a device on and off. I need to add a scheduling functionality to the system wherein I can schedule the events such as switching a device on or off. Also, the app needs to view and delete these schedules. The server is done in Node.js. My budget is maximum INR 6,000 and time is a priority here. Please contact for more info. I want a person who can do this in 1 day. Only bid if you can complete it in the given time.
