Only Help I got was better half helped screed it off as I went.
And just that is an amazing amount of help. Running the mixer and carting the cement is a full time job for 1 person, so the screeding interrupts the flow. If that is being taken care of a lot of the worry is gone and you can just get your "groove" on and keep on mixing.
Was talking to a concrete guy just yesterday, and he was saying he hires a new screed guy every 4 years...burns them out, because screeding is ALWAYS done at "foot" level, bent over. If your guys working the concrete rakes are good, the screed guy doesn't have to move a lot of weight. But if they are removing piles and filling in low spots with the screed, then going back over again to relevel you'll just flat wear them out.
