Advertising is free for seven days, then you can choose to continue for a longer period of time for a small fee.
Sponsorship and tutorials can written by either you or me, or the blog post can be about something different, depending on which is more appropriate. For example, I am currently working on a promotion for
http://www.etsy.com/shop/MyFunnyBuddy, however, because she sells tutorials, I'm not going to post a tutorial. Instead I'm making items from her tutorials, posting the finished products and a review, and encouraging people to visit her shop.
Does that help? :D
