How can I get a job offer in New Zealand?

Hello, My name is Sasan Solimani , I am 31 years old from Iran, I graduated in power electrical engineering and I have 7 years of experiences as a service man engineer for wind turbines type V47, 660kW, I wonder how can I get a job offer from New Zealand does anybody could help me

What does it take to feed into the power grid?

because of the harmonic whatnot of the power grid – separate wind turbines, for example, have to be aligned to the frequency of the circuit to feed into the power grid

I understand this – but what does it take to have this occur?

What’s the least an individual would have to do to be able to do this on a small scale?

for instance, to be able to plug something directly into their wall socket that would be able to sell electricity back into the grid – by reverse-engineering a treadmill for example, resistance to power a motor – to sell energy back into the power grid?

How do you figure how big of a Wind Generator You Need for your home?

Does An Alternator Need To Be Spinning Fast To Produce Electricity.?

I am making a micro hydro system in my backyard but i don’t know if the stream is running fast enough to spin the alternator. How fast does it need to be spinning to produce electricity. Already i have 2 solar panels and a wind turbine but want a bit more power so i thought this would do the job. Please Help.
