A viral game about travel/ flights

we would like to have a viral game to use on our website and/or send out by e-mail to our subscribers. The viral should be about travelling/ flying in which you have to score points and finish levels. The goal of the game should be to score as lot of points as possible and with every level you win a price (like for example a discount on buying flight tickets). The person that has the highest score at the end could win f.e a trip to New York. To collect any winnings or participate one has to leave his e-mailaddress. The viral has to be ready well before the end of this year. All text in the viral will have to be in Dutch. Of course we can translate from English to Dutch If you apply for this job then make sure that you can give us some exaples of what you made before.
