oil leaking 01 Accord 2.3L

[stook02780]

My dad got an oil change at a place with a bad reputation. The next day his oil light comes on, and we noticed oil leaking underneath. He took it back to the place they said his oil pump is bad, gave a price of $350. When I found out about that I had the car immediately towed from that place.

Heres how it looks from underneath: I can't really tell where the leak is coming from. what should we check? pics are large to show detail
