Jquery calender for rental website

NOTE, I only want questions here on Freelancer and i dont not want to be contacted by email or by the website!

Hyrbro (www.hyrbro.se) offers machines for rental. On each product page, there is a calendar that should show booked days and give the customer the opportunity to choose the desired dates for booking.

Please read the requirements specification before leaving a price.

I want a fixed price first and the opportunity to continue to buy adjustments per hour after.
