You could try setting something up on GoFundMe. http://www.gofundme.com/
It will help you reach a wider audience. Have you spoken with the group that you are going with to see if they have ways for volunteers to help raise funds?

What country are you going to, if you don't mind sharing that information?
I went on a night time tour on a beach in Costa Rica once to see the sea turtles hatch. You will really have to walk, possibly for hours in the dark with one of those infrared flashlights, before seeing anything. And you might not see the turtles at all.
At least that was my experience. Even back then, turtle egg poachers were a huge issue.
Sounds like a wonderful life experience. Although I personally couldn't imagine volunteering to do something like that for 2 weeks, though. Seems like the work will be somewhat dangerous and also, monotonous (when it's not being absolutely scary).
Just be safe!
Good luck! Let us know if there is a fund created. I'll contribute!
