maybe you could find something on groupon or apron/vest store,,, while i can't imagine anyone wanting to do this work themselves, its your life & pool,,, here goes: remove the plaster from 99% of pool (s/b, diamond grinders, hi-pressure w/abrasive wtr-blast, aurand scarifiers, etc), make proper conc reprs, install epoxy vertical surfaces w/o runs, drips, or sags,,, not necessary to etch conc in order to apply epoxy unless you've not done it properly & have a clean surface.
do you find it interesting no pool company advocates epoxies in a chlorine environment while sellers do to cost-conscious h/o's-diy-ers ? usually the end user can only see the common denominator as $$$/COST, not value,,, this isn't work i would encourage any diy'er to undertake,,, cost of repairing your f'd up job will be LOTS more than having a pro do it correctly the 1st time but its your $$$, time, & pool,,, ooops, 1 more thing - who do you sue when the job goes in the toilet ? ? ? yourself ? ? ? you don't happen to have a bride who'll want to add her $.02 hourly or daily ?
we repair pool conc as part our work & i own the same tools pool plasterers own,,, i wouldn't attempt to replaster our own pool,,, you deserve your results - nevertheless, good luck,,, post a photo 2yrs after you're done !
ps - is that what you call a pressure washer ? that blue thing on the pool floor ? you gotta be kidding us, right ? what is it - 1,500psi @ 2gpm ? looks electric, too,,, evidently living in las vegas MUST encourage 1 to gamble against the house
