study abroad in Belize

I am raising money to take a study abroad trip to Belize next summer. I am getting my masters in anthropology and will use this trip as part of my masters thesis. I will be going as a research assistant to the professor. We work with sugar cane farmers and try to find ways that the government of Belize can help them. We work with the Sugar Industry Research and Development Institute and the Belize Sugar Industry, writing a report to them of our findings. I do this not just to get a better career but I do it for my family. I was able to afford the trip last time but my family had to make huge sacrifices and I barely afforded it. I have become the only income for my family and I make under 30,000 a year. We had to give up our home so that we could give my son and future children a better life and this trip helps me give them that better future. The 7000 covers 4500 for the flight, food, lodging, and trips while there. 1000 goes for the tuition of the trip, 750 goes for products that I need to buy for the trip (that's how much I spent last time) 500 for spending money and 250 for emergency purposes and 1000 for my wife and son to cover the 3 weeks of bills that need covered while I am gone. Please help me fund a better future for my family.
