Blog Posts for Childcare Site

I manage the website for a Childcare provider in Texas. Their blog is fairly new and we're looking for bloggers to help provide content. We would like posts on subjects like child development, child health, children's fitness, healthy eating for kids, kid activities, educational activities, kid's cooking, etc. If you are a parent or have experience in childcare and can provide posts, we would be interested in hearing your ideas. Initially they are looking to do 1 post per month, but that number may increase as we grow. We're looking to pay about $15 per post and, while we'd like to have some variety, we'll accept more than one post per author. So, just let us know how many posts ideas you have and your bid for them. Before we hire anyone, we'll need to know what you plan to write about and we'll need to see 2 writing samples.
