Hi -
I've been working as a German-to-English translator for over five years now, with additional experience as a translation project manager and technical writer.
In prospecting for my own translation business, I've been I've been doing something similar to your project for a while now. Based on the topic your interested in, I think we could easily automate the process through a combination of RSS feeds, change detection services and keyword searches.
I'm estimating roughly an hour a day to summarize the results for you, but that could end up being less depending on how narrow the topic is. Let me know if you would like to discuss in more detail.
Looking forward to hearing from you.
Best,
Jeff Gary
