Launch tour operator booking engine on website (wordpress)

NOTE: Project has to be completed within 7 days + only accept bids through freelancer - do not contact us if you can not meet our budget! Hi there. We currently have a very simple website, built with Worldpress. We are an online tour operator that sells travel packages to travel agents and customers directly. The idea is the following: 1) Travel agent or customer visits our website and follows link to promotions 2) customer can now start booking different hotels in one reservation (ie. 2 nights in Miami, followed by 4 nights in Orlando, followed by another 2 nights in Miami, etc) 3) customer can see this through a calendar, and sees the different prices that are available per day (different price per day) 4) a custom-made pop up has to be filled out with all required details as we want them 5) guests are given the option to purchase additional services (ie. rental car, etc) **IMPORTANT** we need to really have this custom made, so its important that we are able to set the different hotels, different prices per period, that we can choose what can go in the pop up window etc. Also, we need to be able to block black out perionds etc. Preferably, the system has to send us a notification email that somebody made this booking with those details, so we can actually process it. Another requirement is that the bookings are stored somewhere, and that we can easily extract reports from this database with all information in it. Last but not least, if there is a way to populate invoices and / or vouchers from this system, that would be a BIG plus :-) Let us know if you can do this for us...
