This Hulkbuster armor, created by the folks at Extreme Costumes (an appropriate name) stands 9’6’’ tall, comes complete with electronics, can be walked in, and required over 1600 hours of work. 1600.
That is almost 67 days if you worked around the clock, or 200 days if you just worked a normal 8-hour day, assuming you took no breaks. (The green lasers shooting out of the eyes alone are worth skipping a few coffee breaks here and there.)
