I've done a little bit of market research for a client offering a related service in the same space.

One of the fastest ways to scale is to identify existing networks, build relationships with others who align with your mission, and ask them to ask their own contacts to submit reviews. Make the process as frictionless as possible for everyone asking for help.

Aged care services take many forms: live-in care with varying degrees of medical expertise, live-out care, aging in place, respite services, retirement lifestyle condos, nursing homes, independent living communities, and so on. Each type of service takes a different approach to elder care.

Each type also tends to have its own professional association or network. For example, the American Association of Retired Persons frequently hosts seminars across the USA to help retired people adjust to their new lifestyle, including ones on caregiver services. They might be willing to ask their members to help you get started.

Caregivers themselves can ask their clients to leave reviews on your website. The key here is speed and scale: state and provincial networks can be particularly useful here. For instance, the Ontario Personal Support Workers Association maintains a membership of PSWs who can ask their customers leave reviews on your website.

Finally, charities such as the Alzheimer's Society wants to help seniors find the right care for them by offering resources, education, and support. I imagine one of the purposes of your UGC reviews is to likewise help visitors make the right decision. The Alzheimer's Society might see strategic alignment and open up their network if you start cultivating that relationship.

Let me know if you'd like a call to discuss in greater detail. Hopefully this approach helps jump start your website.

Best,
