The 50-year-old is on the brink of recording a third successive promotion, having delivered back-to-back rises to Crawley, provided the Millers avoid defeat against Aldershot on Saturday.
Evans, who joined the club a year ago, has not had it all his own way at the New York Stadium this season, but is desperate to join the select few managers to have won promotion for the South Yorkshire outfit.
"This is the biggest club I have managed by some distance," he said. "It has got a good fanbase, got some incredible players, so Saturday is a big day for all of us.
"Winning promotion will be the biggest achievement. When I came in people said it was a huge ask.
"There are very few managers who can claim they have taken the club to promotion, but when you can put yourself in the same bracket as the likes of Ian Porterfield, Ronnie Moore and Billy McEwan then you have to say that would be a wonderful achievement."
And Evans insists there's no chance his side will step off the gas against the Shots on Saturday.
"They are not fighting for anything, they are relegated. There's no point me putting any other spin on it," he said.
"Miracles can happen in football, but they are not going to come here and win 6-0 and three other teams lose.
"They will have a freedom to play and that will make them more dangerous, but it will be about what we do on the day.
"There is no complacency because we know the prize. The players know what is at stake. Training in the early part of the week has been as good as it has been all season.
"But we're not complacent. I've issued more warnings than Michael Fish did before the hurricanes because when you think you have achieved in football it has a habit of kicking you."
