We're starting over! Where to begin with a fresh marketing strategy?

We're the US arm of an all-volunteer international nonprofit looking to establish a solid marketing foundation, and we'd love an hour of guidance from a marketing expert to help us understand where to start. We know marketing is essential to growing our reach and impact, but we're not yet sure what pieces need to be in place to do it well.

In this one-hour session, we hope to learn:
What useful information can we glean from the Brand Identity report we received?
What should we prioritize first given limited time and resources?
How to define and reach our key audiences (prospective board members, volunteers, grantees, partners)
Which tools or platforms are worth investing in early on
Common mistakes nonprofits make when building their marketing, and how to avoid them
