just to see I have it right.... if using 1円でも安く, means as cheap as possible 1円でも高く would mean as expensive as possible?
so 一人でも多くの人 is as many people as possible?
so the main sentence. 忙しくて忙しくて, だれでもいいから一人でも多くの人に手伝ってもらいたい。
I think that だれでもいい means anybody.
has the nuance of..
because I am so busy, I want to get help from any and as many people as possible.
It is sort of an idiomatic phrasing, but "as xxxx as possible" is a perfectly fine functional translation. A direct translation of "as xxxx as possible" would use 出来るだけor 出来る限り
