I think the referral link is a great idea - both from a discount perspective and because you are referring us. I'd propose just disclosing exactly that: "here's a referral link, and you get 50% off the first month by using it." If folks are uncomfortable with using it, they presumably can find Fancy Hands' website on their own. Or offer both direct & referral links.
