JM, I wouldn't get the work if I didn't manage the entire business communication spectrum. These projects are less than 15% of total milling of marketing communication projects for the organization.
It all starts with research (employee, current customers and local population). We roll that info into the overall Strategic plan.
From that, we do a MARCOM plan; a very detailed budget detailing timelines, materials used, budgets, etc.
That master document is used to manage all internal and external organization activities, of which music gives me an advantage, in terms of the final product, but, frankly could be eliminated, with minimal negative effects.
Sadly, you're right. The day of the $5,000.00 30-60-10 local jingle package is long gone.
There are ways to do it, but it's TOUGH.
