Viral etc Marketing

I am seeking well-qualified/experienced help in marketing via the internet a draw/raffle for my home in southern Spain, which I need to sell before I can emigrate to join my family in New Zealand. This draw has been set up so as not to infringe Spain’s equivalent of the UK’s Gambling Commission regulations. I am having little success in selling the property via the more conventional channels. The bottom has dropped out of the Spanish property market due to over-supply, the current recession, the strength of the Euro vs the Pound, the tighter mortgage conditions etc.

I have created a website for the house and now need to get the word out across Europe generally but also to zoom in on expat hotspots’ around the world and I believe that world-wide viral marketing would be helpful in creating a fertile seedbed. But perhaps you can suggest other and better solutions

I have a press release in professional preparation which initially will be distributed around some 2,000 media titles, radio stations, property and travel freelance journalists across the UK, and which also will be syndicated to MSN, Yahoo! and Google News, news aggregator sites, such as Newsnow and Moreover etc.

I would be interested to learn how you may be able to help me to spread the word beyond this initial press release and also of course at what cost to me.

Do throw any questions at me if you think necessary. Thank you.
