Targeting families with ageing parents

I'm a marketing consultant helping a senior care solution to market to families with ageing (grand)parents at home. The market is already pretty damn small and niche. My experience is mostly on lifestyle products, business services and cryptocurrency marketing. Having said that, tools and channels I'm familiar with would be mostly community engagement on forums, community groups as well as digital marketing + content marketing.

Some issues I face now is slow conversion and growth rate compared to other things I've marketed before. Another thing is, of course, limited budget as it's a small start-up I'm helping.

I'm already working on each funnel from community to content but I thought perhaps my limited experience/exposure to senior care is also limiting my results. I would also like to pick your smart brains to see if I missed out on a potential channel/platform/idea to explore? :D

Appreciate it!! ^^
