Like kijiji or Craig's list or local newspapers online? Is there a wellness webpage in your town/city? Have you built a Facebook page a TikTok to advertise, etc? How about a one page ad on one piece of paper you photocopy with your phone number multiple times across the bottom so people can tear off if they are interested. Lots of grocery stores have a billboard for local community services like putting up informal ads with phone numbers (or email addresses) on them. That would be cheap. Do you have a friend who could drive you around to community billboards? Or new age independent bookstores?
I worked in a gift shop in a swanky part of town (the Glebe). A local tarot reader advertised in the store and would book appointments for each Saturday and meet people in the basement of the gift shop for their tarot reading. I don't know how much money she gave to the owners of the gift shop per client but it was worth the gift shop owners' while to put her advertisement front and center in their store. Maybe there are partnerships like that you can create? You could go from store to store to store on a Saturday and book clients accordingly.
Can you start a go fund me for repair of your car?
I just remember my brother found a kayak paddle on the river when he was out paddling. I put up "lost kayak paddle" that day on one or both of the first two sites I mentioned above and got a responce within a day from the owner of the paddle. It is truly amazing how connected we all are.
I have no experience in Marketing... I just feel for ya.
And remember, when you are going through hell keep going!!!!
