Drainage issues under shed

[netty]

I have a shed in my backyard and having drainage issues under shed and the ramp. I am in the process of replacing a ramp that got rotted out. I have dug drainage ditches but have not placed any pipes. My biggest concern is routing water from under ramp and shed. It has turned into a diy because 3 companies have come out to look but never got back to me with service or quotes. I live in NC and not uncommon to get heavy rain fall.
There are pictures of front, side and back of shed.
