Agree with comments below. Just give us a topic or, if possible, a few bullet points. I'm very good at taking rough ideas and translating them into inviting-to-read blog articles or podcasts. But I need at least a general idea of your topic and/or goal. It would help to know your intended audience, too. Thanks in advance for clarifying.
We need to have more information on the topics for which you want articles and podcasts. Contests are competitions and therefore we need to know what form the submission should take, such as an original sample article pertaining to your selected topic.
