Hello Kaustubh Agashe,
Maybe this is a template you could use:
News and Content Template

Still you need to make your own adjustments.
You definitely are going to need some administration of the quotes and also you need to find a way to prevent the application of using the same quote multiple times in a few days, so think about how you set up the quote entity.
Hope this helps,
Good luck!
