# Let's Scope It with Josh Cross

> Twenty minutes to figure out what you need and whether I'm the right person to build it. Tell me what you're working on and what's slowing it down. I'll tell you what it would take and what comes first, and if I'm not the right fit I'll say so before you've spent a dollar. Bring the project or decision you want to move on, and we'll leave with a next step.
