# Finish-line Introduction Call with Jeffrey Long

> Have a problem requiring more than an hour? Let's talk! No charge, and we'll cover the six-session coaching engagement ($850). We'll review what you're trying to finish, whether I'm the right person to help you finish it, and how the six sessions would actually run. If what you need is an answer to a specific question rather than someone alongside you for a few months, book a consulting hour instead — that's the faster and cheaper path.
