If you go to https://tallowedandfree.com/ website you notice on the top they accept BTC. When I tried paying it redirected to crypto.com payment processor 🤢🤮 I gave them feedback to use BTCPay and currently the owner finds an alternative to difficult to use technically.

If you guys can offer an easy to use service so she can accept Bitcoin on chain or lightning it will help her business. Try reaching out to her and see if you can develop a trial partnership.
