Paint original dark brown doors to white - please help

[Annakool 0]

Hello all,

Our original doors and door frames are all brown colour.   Before starting renovation work we had told our contractor that we need all doors and skirting colour to be changed to off white.  Now he is saying cannot change dark brown to white.  He is saying " only way is to put a white oil paint coat on the brown doors and that will coating look very thick and the doors will look ugly".   He is saying can change white doors to brown BUT cannot change brown doors to white. ( Now He is charging $2000 for staining and varnishing brown doors to walnut colour - 8 doors and house skirting).   We wanted cream colour doors and skirting.

Please please help.
