Build relevant content on a list of urls and include a back link.

I have a website involved in a specialized niche, and have collected a list of 1837 conversations where it may be possible to get a back link to one of my pages. I will provide you the list of these 1837 urls, and I ask you work to enter the conversation, add content, and include a back link with one of the anchor texts I provide to you. You will indicate your understanding of this project requirements (and specifically, it is NOT profile creation with links, classified ad postings, forum profiles, but profiles will be needed in order to post to many of these urls.) by starting your proposal repy with the terms "I understand the requirement of posting on some of the 1837 urls you will provide." For this project, you will work through the list sequentially until you achieve 300 published links. This project is thus to enter the conversation on 1,837 pages, and post 300 backlinks on the ones where possible. Many are blog comment format, others are huffpost style sites with comments enabled.
