They texted this message to me: "Elaine let me know if 6 hours a week can work for u. pay starts 5 days later reply yes for details Out for stop"
There's no identifying info, so idk who this is, or how they got my name and number.

NEVER, NEVER, but NEVER return calls or texts to persons or numbers you don't recognize.  It's a sure fire way to download a virus, or get caught up in some sort of scam.  Forward the call or text to *7726 (SPAM).  This works for AT&T, T-Mobile, Verizon, Sprint or Bell.  Don't know about other providers.
