6 month old needs 2 open heart surgeries

My 6 month old was diagnosed with a ventricular septal defect, and an atrial septal defect on mothers day this year. The holes they say are too big to do in one surgery without effecting her in a negative way. I make "too much money" to get assistance, but not enough money to actually cover these myself. She is my first daughter, and I am a single mother. If anybody could please help me try to reach my goal, they want to schedule her for her first operation on July 5th, 2013.  I have a feeling this will not be obtainable but am hoping it will be. She is my pride and joy, please help me keep her alive.
