My site is still in development, but I believe it will be exactly what you need. We launched just last week and are currently in the process of building our freelancer database. We focus on American freelancers
. If you are looking for community building, you can submit a guest post about what you do, create a profile and post announcements, or even participate in our forum. Again, we are brand-new and are restricted to American freelancers, those looking to hire them, and those looking to provide services for them. Here is the site:
We also have a G+ group -- https://plus.google.com/u/0/communities/112125382840327680718
And here is another active group: https://plus.google.com/u/0/communities/101576487245787716833
I'd love to discuss other ways we can help you reach your community development needs.
