How do I get involved with Project Children Northern Ireland?

Some people in my area are going to America today with the project and I want to know how to do it for next year, I've been on the website but it doesn't say how to get involved. Also if anyone who has been on the trip in previous years could maybe tell me a bit about their experience, did they like it, how much did it cost etc. Any help would be much appreciated!How do I get involved with Project Children Northern Ireland?Yes you must
