There is a great website called ‘Sparked… microvolunteering by the Extraordinaries’ that offers micro volunteering on line.
As a Not For Profit, you post challenges, and volunteers provide solutions.
The skills available include marketing, social media, web development, branding… the list goes on and on.
I’ve used them to develop our new logo, and encourage you to give them a try soon

Hi Chris,
Was looking at my past Sparked Challenges and noticed you are using the logo for your Sparked account. Glad you are using the logo. Here’s a scaled down version for your sparked account. http://dl.dropbox.com/u/1433209/lead_logo_small.gif
Cheers,
