How much does it cost to replaster a pool?

Had my pool re-plastered. Found a way to save lots of $. Not trying to blast any pool builders or discredit them. There are lots of reputable pool builders out there that are well worth the extra investment. Unfortunatley there's many people out there that bare this extra expense and they can't afford it. I'm just showing how I was able to save. I'm sure it's a gamble. It may or may not last but it is an option.
