Need multiple blog posts on simple elementary math concepts

I need someone who can create simple elementary math contents (e.g, how to calculate the area of a circle, etc.) but with two important features: 1. It should be drafted beautifully and well organized. and 2. should include nice ORIGINAL graphics (most often if you are a master of MS Power Point) that should do it.

If you are such a person, please share with me at least 4 of the best articles that qualifies the two axioms above. and also let me know how much you charge for any of them.
