Mate, what a brilliant idea!!! I really hope its a big success so you can help that family out!
Hmmm, maybe an idea or 2...
Approach local business for things to raffle off? what about getting the local rag in to do a story on the meet? that way, people can donate after reading the story.
For a good cause like this im sure there will be enough interest and good hearted people that will help out!
