For starters take the ticket count off the site, seeing so few sold will put people off as they will think the draw wont happen. You will need get the cars gone and the photos of winners out there. Advertise, advertise, advertise. Get it on backroads, put ads in buy and sell, donedeal, adverts.ie. Get it out on boards.ie. Get the Irish YouTubers to advertise it, by throwing them a few free tickets to give away. Once you get a customer base it will run itself, but getting the word out is what needed. A referral scheme like refer a friend and get a free ticket would be good and spread the word.
