And when/if you decide to do one, enroll in an established university like UON. There are some makeshift universities and academically young universities offering Phds without the requisite resources and personnel.
A Phd. from a university like UON is 'solid' but in some departments like Engineering & IT you will be frustrated for like 10 years. I guess it the faculty's way of reducing Phds in the market. Best solution is doing the Phd. outside the country which is tricky if you are self sponsored, your employer is not on board and you have a family!
Never count on making a good sale. Have the purchase price be so attractive that even a mediocre sale gives good returns.
