Ticket booking module for the joomla / virtuemart

I need to build ticket booking system for the joomla virtuemart . 1. Online Booking System 2. client will be able to chose a sit or more than just one sit and no one will be able to book that sit on the same time while the client on the order process. 3. To book seat customer will click on the seat and it's will gonna change the color , if he change him mind he click again and seat will be available again . Similar like here [login to view URL] . You see stage and you see available seats , in gray color seats are already booked and , in red what you have already booked . There will be around 800 seats . Seats as well will have different prices . I will need to have an option import tickets from excel so don't need to enter them manually . Please bid if you have an experience on such work and when we finish this project there later will need to add 3 different locations so I will gonna hire you again to add extra stages .
