Hello,
As the static website's URL isn't provided yet, I assume that some of the pages' layout is different from others. With this, I believe creation of a few page templates would be needed.
That being said, as I have an extensive knowledge and experience (7+ years) with the Wordpress platform, here's what I will do to achieve the fulfillment of what is required:
1. Copy and paste the article
2. Make sure the article matches the layout of the static page
3. Tag the article appropriately
4. Properly categorize each article
5. Pick an image from a stock library that will be provided and add it accordingly to an article
I'll make sure that each of the 2300 article's quality is at least the same quality as the static one.
Since I haven't seen the static site yet, I can't really tell how many days it would take, but 30 days might be sufficient enough.
Looking forward to getting some feedback from you soon.
