Small linking form on html page

Hi on the site http : // the peech . co . za/ (without the spaces) I have a small booking item at the top left called "QUICK AVAILABILITY REQUEST" at the moment it just emails me the dates when a person would like to stay.

We also have a seperate booking site at : http : // www . nightsbridge . co .za / bridge/ book?bbid=10216
on this page if you selct dates you will see the url changes to:
https://www.nightsbridge.co.za/bridge/book?action=2&bbid=10216&startdate=2011-05-18&enddate=2011-05-19

notice the "startdate=2011-05-18&enddate=2011-05-19" at the end of the url.

Can we edit the form on my site so that if a user selects arrival and leave dates on the "QUICK AVAILABILITY REQUEST"  form it opens the nightsbridgepage with those dates set?

also can the dates automatically start at todays date?
