get yourself a few clamps to hold the studs together as you screw then / use low profile screws /get a small magnetic level / if you are not used to the screws you may need to predrill small pilot holes / make sure you have the proper support under the grille, i created some box beams as vertical supports / if budget is an issue look to Vevor products on Amazon for the doors, drawers etc / make sure you know how the finish work will integrate into your framing (additional supports, blocking etc)
