Start a conversation
A conversation, or even a quick ideation session, is a great way to start a solutioning effort with minimal risk or expense. It should allow for quick assessment of an idea or desired project.
In the spirit of agile cooperation, this kind of evaluation is renewed after each iteration - or not. A decision is made to continue down the current path, adjust course or cut losses. Minimal risk and expenditure to test hypothesis.
That's why the first couple of sessions are no charge. If a few minutes (or hours) don't illuminate a path forward together then there's no reason for you to lose any more time.
