I've had the best luck with FB groups, networking(local or through social media), referrals.

And always check social media for red flags and I agree with Vince, always meet a person.  

Have you talked to any social service agencies about this yet?

Guests love this upsell for the experience provided, they are more likely to share on social media, you can use the decorations as marketing, build relationships with local vendors, and provide extra income for your team. 

You're running a business...you are not a social services provider. 

I think she is equally responsible if she is 50 / 50 ownership per the offering and through thier own discussions on podcasts, social etc. 

Things like a website, an email at your domain and credible social accounts (even small things like a profile pic and bio) can show you are a legitimate business.

I have a client in KC that rents a large home in the urban core to a social service org in the area that feed him tenants.

Door knock, cold call/text, mailers, social media, etc. 

If the management fees stay in Sch-E, it is exposed to ordinary income both at Federal and state level, which is way higher than SE taxes of 9.55% (15.75-6.2 (personal social tax already maxed out)).2.
