# 15-Min Discovery Call — Sir Brown AD with Sir Brown AD

> A quick, focused call to see if I'm the right fit for your project. In 15 minutes, we'll cover: - What you're trying to build (website, fix, or upgrade) - Your rough timeline and budget range - Whether it's something I can take on - Clear next steps — either a proposal or a referral elsewhere This isn't a full planning session — it's a fast fit-check so neither of us wastes time. Come with a rough idea of what you need, even if it's not fully formed yet. Need more time to go deep on a complex project? Mention that when booking and we can schedule a longer follow-up. Prefer async first? Reach me at browncemmanuel@gmail.com or WhatsApp before the call.
