We have a neighborhood listserv that is used for this type of thing.

I’ve seen posts in mom groups, but instead of posting your kid’s number, you can ask people to contact you. Then you can connect them to your daughter

I was Facebook shamed for posting my 15 year old daughter’s babysitting flyer that contained her cell phone number to a a neighborhood group for being unsafe. How are other teenagers advertising other than word of mouth? She’s really looking for more babysitting jobs to earn some money this summer. During the school year she’s usually so busy with studying and running, but she has some free time this summer and would like to earn some money. Any other suggestions to help her earn money?
