The car is fixed. YAY!!

sooo my radiator sprung a leak and after some consideration I spent $283 that I have saved for christmas on a new one. Two days later, my water pump went out. Estimate? $324 . So my car is parked. I dont dare move it with the water pump out. The water is not circulating thru the motor as I understand it and it can overheat in no time at all. A friend from church got a guy to come and look at it and he told me it was the water pump ( I knew that) and told Charlie , the guy from church, that he would tow the car to his house and do it for $100 plus parts. The thing is that I know nothing about this guy, he doesnt speak english and Charlie says he's good but I dont know that Charlie knows anything himself. I dont know him that well. Charlie was also planning on paying for it himself. I can't allow that, It is sweet of him but I would feel obligated and like I was taking advantage of a man with a crush on me. So I turned him down gently. My son in law type person has offered to do it and at least I know he has done mechanical work before. I will pray that it goes well. The timing belt has to be removed and that can be tricky. If you dont get it back on in the position it was in when you take it off your car wont run. I will be replacing it since it has to be removed anyway. I'm being proactive here. So I have bought the parts and am just waiting for the weekend when the son in law type comes to visit his son ( my grandson) and works on the car. Please send good thoughts about my car. I can't replace it and I can't afford to have shops working on it at this time. This has to work.
