Help Paola Fix Her Car AC for Her Kids' Safety.

Hello there, my name is Paola and I am a mother of 5. Economy is tough and even my small business has suffered. I am down to 1 to 2 bookings a month and it has barely been enough to pay bills. I usually do deliveries to accomodate the business loses. However, my car A/C has gone out and the only one that has found the part is my dealership. They are asking for a $500 payment to fix it that I have not been able to save as much as I have tried since May. I am asking for your help to help me fix my A/C. I am only asking for what the dealership needs. At the same time my biggest concern is that only my front windows go down and by the time I get to my kids school for pick up my 3 month old and 2 year old are drenched in sweat. I am extremely concern for their health but have absolutely no help or where to leave them while I pick up my other children. I absolutely hate asking for help as I have always been very independent but I cannot keep seeing my babies like this. Im so afraid every time I get in the car thinking they'll have a heat stroke specially the baby that is turned the other way and doesnt even get a front window breeze. Any $1 helps and if you can't help with $1 please send prayers that God sends clients my way so my calendar can be full.

God bless everyone and thank you in advance for your help or prayers!!
