Windows😵

Not sure if this is the place for this. If not let me know.

I need windows replaced on my house. I’ve called 2 “local” companies that sent salesman dressed like business men to my house, just to tell me 6 windows would be 15k-25k. Both companies said they can try to match quotes from other companies.

I’m looking for a contractor that I can hire to replace my windows. I don’t want to pay some salesman’s high ass commission for some $500 windows. I could get windows from Menards/HD for that price. Anyone with any knowledge in this field?

I live about 40 minutes outside STL.
