Hard to answer the ideas question without more context, but I'd focus on ideas related to something you are passionate/knowledgeable/curious/have an opinion about. It's so much easier to write a piece of content when you actually care about the topic and have something add to what's already out there.

As for writing, I find it super helpful to have a formula that I can repeat for multiple articles... again, depends on the topics you're writing about. Give yourself timeframes - you'll probably fail to stay within the limits at first, but it can often help to keep you focused.
