Email us. A human reads it.

Whatever you have. But if you want the fastest useful answer: what you're building, who it's for, and roughly when you need it.

Links to anything that exists help too: a doc, a sketch, a competitor you like. Two paragraphs beats a twenty-page brief.

We read it, ask a couple of questions, and come back with either a scoped first slice and a price, or an honest "we're not the right fit" with a suggestion of who might be.
