31074 Online Booking! Out of the Box

Hi, I need OUT OF THE BOX thinking for this project! I've a building with apartments, offices, shops for sale. The building is under construction. As the building moves towards completion, I want to race up the bookings of the apartments, offices and shops. So I need creative adeas for how to go about it. That is, you tell me how can I make use of the web for it. You should gimme the details that prove that this idea is implementable and you can do it really well. But again, think OUT OF THE BOX! I know lot of online booking systems. But probably online payments as high as these might not be possible for everyone through credit card. I wouldn't use any other payment method either. So you hit me with your ideas and creativity! Regards, Harix
