Going back to Ethiopia in July

I will be going back to Ethiopia next month and I am worried we will not have enough money. It is harder than I thought it would be to raise money consistently. I have been a volunteer for as long as I can remember, but always for pre-existing organizations. I have worked on various fundraisers, made some money and then did not worry about how that particular organization gets its money the rest of the year. I was not seeing the big picture. I am constantly trying to think of new ways to raise money. While prospectively we don't really need a lot of money to run the school (it will be $2,000.00 a month soon), it is not easy for a small organization like ours to bring in that amount monthly.
