An interesting article about maximizing your freelancing exposure through a press release about research you've performed or skills you've gained:
"If you have an interesting story to tell, a press release will help you to make newspaper editors aware of it.
Maybe you recently won an award. Maybe you stumbled upon some interesting information in the field you work in. Or maybe your design contributed towards some kind of achievement on behalf of your client.
Depending on the scale and content of your story, you can send your press release to marketing websites, marketing magazines, the relevant trade press, the regional press, and even the business section of the national press."
Examples:
