doors custom

[Joker2021]

hello

I am planning to replace the doors in the bedroom and bathroom as they are worn out and also paint them including the existing door frame.

I understand bunnings can do custom size doors if needed but would like to know if they will do the hole for the door lock including the sides for the door hinges etc or would I need to do it myself. 

In terms of painting,  for two coates would 4 litres would be enough to paint 5 door frames and another 4 litres for the doors?

Regards
