You want a quick-fix.
You don't need ongoing marketing input. You simply want to re-launch a product or service or update your corporate identity. Or maybe it's time for a more effective website, a brochure or some PR.
My ad-hoc service is ideal for this. I come in, ask questions, evaluate your requirements, then go away and prepare a quote. If I need to involve other members of my network, such as designers, I don't mark up their charges. You just pay for my time and, separately, theirs, so you'll be pleasantly surprised by the cost.
Then I deliver the agreed projects on time and on budget.
