Rule #1 of pricing: Never justify your rate. Let your service/product justify it. The moment you start justifying your rate, you’re negotiating your rate and it’s no longer the rate.
Sounds like you’re free to start accepting some of that other work you had to turn down.
Lolwut? (Edit to clarify: “can’t wait” contradicts “sue me” because that’s such a huge time commitment)
You aren’t getting sued until you’re being sued. Keep on with what you’re doing and ignore the threats.
