That sounds fine to me, Void. We should dump the initial burst of articles on to the blog before we have any dupe posts, give Google a chance to crawl it and then do some of the "guest blogger" posts. I know there is some contention as to whether Google punishes duplicate content, so I would say to ElDinero to also watch the numbers on his other posts and see how they match up to ones duped here. That way, he isn't screwing himself to help us out. Just something to keep an eye on as we go in. I appreciate your offer to give us some posts, Dinero. Oh, and as for the link the in the posts, don't bother. It won't help your content to have a link to the same content. I don't want you to throw off your readers for our sake. If we are going to take your content to begin with, it would be uncool for us to expet you to make yours look bad while we don't reciprocate. However, if you ever want to link some keywords to other blog posts of ours, I won't object.
