Collecting votes for car design contest

Greetings to all freelancers I'm participating in a car design contest hosted by a car company. The votes are accumulated by clicking the "Like" button when visiting the, I think prerequisite is the voter to have a Facebook account. In one month period I managed to gather 700 votes but I don't have enough time more to spend on advertising my design. The car in the 1st place has already 4100 votes and the contest ends in 13 December 2013, at 13:00 CET. Please note that the contest started in May of 2012 and I was informed only a month ago. And without much effort, just by advertising in in facebook groups and some blogs I already collected 700 votes and I'm currently at the 7th place. Currently the images of all the designs are not shown on the website for some reason, but I can give you the 3d renders in case you want to post the design or advertise it somewhere. The successful candidate required to advertise and promote my design and reach it at least up to the 3rd place. I'm willing to pay up to 50% of the winning prize. The winning prize by the company is as follows. 1st Place: 5000€ 2nd Place: 3000€ 3rd Place: 1000€ So the better position, the more the successful candidate will earn. To show good will the payment will be as follows. 250€ as soon my votes exceed 100 votes of the car located in the 3rd place + 250€ by the end of the contest if my car finishes in 3rd place. 500€ (plus 250€ as aforementioned) as soon my votes exceed 100 votes of the car located in the 2nd place + 750€ by the end of the contest if my car finishes in 2nd place. 750€ (plus 250€ + 500€ as aforementioned) as soon my votes exceed 100 votes of the car located in the 1st place + 1000€ if my design will finish at 1st place. Please mention any relevant project you did in the past or how you willing make the job done. Regards, Greg.
