Taproot+ is a good source for online volunteers. I’ve used them for mail campaign advice and infographic development. Recently they’ve added this new feature:
“We’ve made it even quicker for your organization to access professional resources with our newest feature: Virtual Office Hours.
Virtual Office Hours connects nonprofits with skilled professionals for one hour, one-on-one consultative sessions to brainstorm, troubleshoot, and diagnose organizational challenges. Here’s how to request a consultation session:
Choose a session from our list of topics (or create your own!)
Pick a few time slots you are available for the call
Join the virtual call at the scheduled time to connect with an expert
There’s no limit to the number of sessions you can request, so go ahead and request a Virtual Office Hours session today.”
