I need a Holiday Home Booking Script. Let me know, if you have a readymade one.&nbsp;<br /><br />Must show availability of booking online to customers (colour coding in a calendar), allow them to click on dates, calculate costs and submit an enquiry.  Must allow them to select extras (like collection from airport) too for additional cost. &nbsp;<br /><br />Must have an admin panel for us where we can allocate notes against a booking, run reports to see bookings in a time period etc...<br /><br />Must also link to a Google Calendar.<br /><br />I can give you examples from programs that already exist if you need more info.<br />
