Spare-Change Circus: Walking Coins on a (Vertical!) 'High Wire' - is there an easier way to make the base and also is there a way that i could be able to buy the base.

As the experiment tells you, you can build the base with wood, which is much simpler. You could also build it with some good sturdy display board or corrugated card board.

I'm not aware of anywhere you could just purchase something like this.

thanks

how are the coins supposed to walk up the wire if they are not magnetic? is any data to which i can compare?

Think about and research "electro-magnets". Copper is a metal that can't be magnetized in the sense that it won't act like a magnet in the absense of an electric field or current flow, but most electromagnets use a lot of copper wire to create a magnetic field.
