Does the Islamic religion permit a woman to work as a saleswoman in a shop selling women's and children's clothing all day long?

There is no objection to a woman opening a shop to sell women's and children's clothing. It is preferable that she manage it herself due to her need. However, if circumstances necessitate dealing with a man, it must be within the bounds of Islamic law: no softness in speech, adherence to modest dress, limiting conversation to what is necessary, and no private seclusion.
