If you’re leaning toward “I can’t take this job on,” you’re allowed to make that decision. Saying what you might be able to do before seeing the metal isn’t the same as confirming you can deliver the finished job. The anxiety deserves attention, but there’s also a practical problem here: you haven’t inspected the material, the requests are changing, and you and the customer don’t have a clear agreement about timing. You have three reasonable options: 1. Step away now. If you already know you don’t want the job, communicate that before Friday. You don’t have to attend just to be pressured into agreeing. 2. Make Friday an assessment only. State beforehand: “I’m coming to inspect the metal and determine whether this is something I can do. I cannot promise the work or a completion date.” 3. Refer him elsewhere. You can ask another professional whether they’re interested, but don’t promise their availability, pricing, or results. My recommendation: if you wouldn’t want this job even with a reasonable deadline and clear expectations, step away. If those changes would make you comfortable, offer the assessment with firm boundaries. You could send: “After thinking through the project and what it requires, I’ve realized I’m not able to commit to completing this job. When we first spoke, I discussed possibilities before seeing the metal, and I should have been clearer that I hadn’t confirmed what I could do. I wanted to let you know before Friday so you can make other arrangements. I’m sorry for the inconvenience.” If he pushes back: “I understand you’re disappointed, but I’m unable to take the project on.” If money has already changed hands or anything has been signed, address that directly as part of closing things out. For this morning, choose your next action instead of trying to solve the whole project in your head. Write the message, take a few slow breaths, and send it once you’re settled. You can take responsibility for being clearer without forcing yourself to deliver work you aren’t confident you can do.
