Raise your price dramatically, she may go away, she gave you a hint about that already. Implement a new rule that the first hour consultation is free, all other is invoiced at a high price. Track it, invoice her and insist on incremental payment or no more work. Meetings with endless questions and no decisions now make you money. You get to choose how your business operates.

Target market the stores and people in richer neighborhoods, like for the Phoenix AZ metro area you would target Scottsdale and Paradise Valley and maybe Fountain Hills and Ahwatukee. Also, try to hook in with some YouTube/instagram chefs, if their followers see your board being used, or even hung on the wall in the background, they will ask where it came from and likely order ones for themselves.

Talk to a CPA about these things: S corp, LLC filing as S corp, solo 401k, and keeping money in your business. Perhaps spend more on marketing to get more leads/sales if you are in a place where you can scale up your business.
