The Demons mentor has coached two 17-and-under sides to a grand final, but Sunday's A-grade contest is another step up.
“I'm super proud of the group in getting through to the grand final,” Orchard said.
“I set a goal at the start of the season to reach a preliminary final and I guess anything from here is a bonus really.
“But in saying that, we still have a job to do and we can't wait to get out there on Sunday.”
The job that awaits United is traversing pass the rock solid outfit that is Seymour.
From two attempts, Orchard's side is yet to beat the Lions this season.
They drew in round nine and the Lions got the chocolates in the qualifying final three weeks ago.
In that match, Seymour got the better start in the first half, roaring out to a 26-17 lead at half-time.
“We can't let them get an early start,” Orchard said.
“You just can't afford to play catch up, especially in a grand final.
“It's all about grabbing the advantage early and slowly building from there.”
But United will be certain to lean on their most recent wins since that loss to Seymour in the opening round of finals.
The Demons have played through two gripping overtime matches, with the pressure of those matches set to boost the confidence of Orchard's side.
Along with their recent wins, United's group of experienced heads will play a vital role in Sunday's match.
Bree Hanslow, Kara Blizzard and Liv Hall have been in this position before and will help guide and mentor youngster Jemma Hall through the midcourt.
Meanwhile, recent Wellman Family Medal winner Jess Barnes and Tamara Skinner will be leading the way in goals with their talents.
And impressive teenage defenders Laura Cole and Liv Kirby will lean on their grand final experiences from juniors.
“The girls are pumped, but they're still pretty calm and they understand it's business as usual,” Orchard said.
Sunday's grand final at Deakin Reserve will begin at 2.40 pm.
