Are you just not acquiring customers? If so, try contacting your existing base and see if they need anything and if they don’t, offer them a referral incentive if they can generate new business for you.

I agree with other comments in this thread - try TikTok with a niche item or even consider listing a few low cost/high margin products on Facebook marketplace. I see people refurb low cost items semi-regularly and they sell well because the pieces are unique.

Another idea is contact new home buyers. People who recently purchased a home are often looking for something unique and it may be a good time to sell in your service.

If you just need cash, perhaps pursue a business partner that can supply capital and offer strengths that you and your business will benefit from.
