How are you guys making this sustainable

I have a marketing business in central Florida but every client I talk to just wants 1k a month for video and marketing services or hands it off to someone they already employ. Then even the 1k a month ones still spend hours on the phone quizzing me like 1k could change their business. I explain the outcome I have a load of different tech and options and it’s always like naw. One of the businesses THAT APPROACHED ME turned around and said no we aren’t interested an gave it to a PMs wife (they do 10 million in gross.) so I’m just wondering what to do here or if I should just give up.
