I know in southern Indiana they can run from $15.00 up to $50.00 - $60.00 depending on the kind of koi, and the condition of the fish.
It all depends on the size and if you are including the cost of fish. Mine, not including fish, cost about $120 and it is 15x15x2 feet.
Koi is a type of fish. Just don't put koi in the pond and it will not be a koi pond.

The size of the koi will depend on many factors such as what type of koi it is, how much and what you feed it and the size of the aquarium or pond you keep it in.
Heaps if you want to do it properly. Over AU$2000.00.

You can definitely install a pond pump in a Koi Fish Pond. http://www.coloradokoi.com/ has a lot of valuable information about caring for your Koi Fish Pond!
No it should not be a problem. Just clean the pond.
My koi pond is black, with stone sides. . .to me this makes the fish very visible I would google image "koi pond" to get a better idea. At koi shows they are displayed in blue tubs. Web sites that have koi for sale show all their koi on blue backgrounds. Some koi have black in them and some are completely black. With a black background the black fish disappears.

from a small business that specialises in ponds or someone who has a pond and koi fry.
no koi fish do not need a lot of space 10 to 12 of them are often put into a small pond
I have 7 Koi fish in a pond, 1 of the fish constanly stays on the surface and swims in circles. what does this mean
