Project Budget (USD)
$100 - $100

Project Description:
Our hotel website has different prices for May, June, July, August, September 1-15th, September 16-30th and October.
But we also change our prices each year. If i change now the prices it effects also THIS years prices (2012) - which is bad.
This we need to solve.

In WP Backend there is the "Pricing"-Tab.
Here we change the prices by clicking on "Yearly". Here we should have
a additional drop down selection for year 2012/2013/2014 and so on, which
adds the new price with year to the database.
Then i should be able to set prices for October 2012.... and client gets these prices for 2012
or if he reserves for October 2013 he gets the correct price for 2013.
