Nothing wrong at all with it! My Ex-Step-MIL (That's always a mouthful) ran her own cleaning service in Hot Springs, AR.
She started by cleaning a few houses part time for a maid service. She got laid off at some point, but some of her customers wanted HER, not the company she worked for.
Word got around, she got a few more houses, then a couple of business contracts and before she could blink, she had 16 women working for her and a lucrative business that has since allowed her to retire extra early (she's only 48) with a boat & two very large, very nice houses, one on Lake Catherine, one on Hamilton.

on the positive interview!
