Hi Guys, I have been asked to revamp this site

http://www.villaonthelake.com/calendar.asp...

As the link shows it has an ASP calendar which highlights the dates rates & if it is booked or not. It also links to a booking system.
What I want to know is there a block that currently does this on 5.7 or is there a way I can take the ASP calendar and integrate it into concrete5 ?

Its something that would be SO useful for rental sites but not something I can see currently.
Any tips greatly appreciated.
