Hand painted kitchen.

Hi guys. I havent used water-based for kitchens yet so looking advice from those who have please.

How much paint do I need for a 10 door kitchen, 4 side panels, small cornice and around 6 metres of kicker ? Customer thinking Eggshell or Satin.
I am thinking of Helmi or BM and will need primed too. Also tape recommendations and other tips welcome.
P.s I dont have any racking system. Thanks.
