2 different chairs, same question.

Hi, newbie here.
I'm helping a family member who's been faced with some difficult times. Helping her raise some funds. She has a 5 chairs I have a hunch are valuable or T least desirable to someone.
The 2 orange Domore chairs are in fantastic condition. The other 3 " louis bursk" need complete overhaul but seem to have good bones.
The tag on the louis bursk says
" made for Miller Desk & Safe company 1957"
"Manufactured by louis r bursk in Los Angeles
I naively suggested/thought to just have the 3 reupholstered but after getting a cpl quotes I'm not so sure it will benefit her goal of fundraising.
My questions are the same for both styles,
What's the desirability, current market prices, best avenue to sell them at? Thank you in advance. I have many many more photos of each chairs.
