front end damage idle and stall problems

So I hit a light pole/ swiped it on the front right side of the
car. The side part of the headlight glass is broken the
bumper is sagging slightly and the body over the tire got
crushed in and was hitting the tire ( before the guy who
towed my car hammered it off). So first I tried to drive it
into a parking spot but the car turned off, not the battery.
So I turned it off and on again and I could drive like 2
inches every time I turned it off and on. I let it sit for like 2
hours and came back and noticed that something
brownish to light brownish had been leaking under the
front end of the car and tried to turn it back on, kept it in
park and it stayed on this time but the idle was up and
down and up down and sounded like the engine was
revving so I turned it off and called someone to tow it to
my house and he was able to start it, drive it in reverse out
of the parking spot and drive it forward onto the tow truck.
So my question is this... I'm moving to Kansas City in 5
days and was supposed to drive there. I literally just paid
1400 bucks to get a coolant and oil leak fixed and I need
to know what the problem with my car is and how much is
it going to cost?
