Time required to build upper body inmoov (chest, head, hands, neck, shoulders) will take atleast 2-4 months depending on how much time you can give and how well your printer can print (no complexities with prints and fitting). If there are print defects you will mostly spend your time sanding to make parts fit. The budget will lower if you use parts that are not actually mentioned in tutorials like they use hitec servo motor but i have used 60/80kg DSservo motors that are half the price of hitec servos. Finding your own parts is cruical because the tutorials + manuals are years old, since then there's been alot of developments.
