Looking for resources, communities etc to help find viable clients as a Wordpress Web Designer and Graphic Designer at Logogr.am
If you are going to use Social Media Marketing. I would recommend you create a Pinterest wall of your work and back link them to your site. Try that.
Ill answer your question with a question, then I can answer it. Are you looking to create an email blast and capture the attention of said prospects in this manner, ie: bulk marketing, or are you looking for more qualified leads you personally reach out to on a 1 on 1 basis (either by phone, in person or video messaging such as Skype, Go To Meeting, etc)?
Depending on your answer there are a couple very effective ways to approach this....of course that's all dependent on the quality of your work.
