1996 Toyota Camry Power Steering Leak

Steering problem
1996 Toyota Camry Automatic

I have a slow leak in my power steering. I have been added fluids to the car every 2 weeks. I took it in to the shop today and first they told me that everything was leaking the oil, power steering, radiator and also the trasmission. Then I was told that I had too must oil on the bottom of the car and they had to clean it to be able to tell me pinpoints $50.

Now after that they told me that the power steering in leaking from the Rack and pinion and I need it replace est. $900. Do that should right? I heard the tech tell someone else that he couldn't pinpoint were the power steering was leaking so I would have to replace the whole thing.

Also they said that the valve cover to the gasket was leaking oil est. $170? I haven't noticed any oil leaks is that uncommon? Could this be something I can do on my own?

And lastly he told me that me Constant-velocity axle on the front driver side needs to be replaced it has a tear in it est cost $280. Do that sound about right?

I was layed off in October and I start a new job on Monday and I wanted to get the car in good working order but at this time I don't have the money to get it repaired. What can I do.

Thanks
