Article writer about ecommerce subjects

I am after articles about ecommerce and shopping carts. These will be aimed at people who have their own online store or are thinking of setting one up. Articles should be approx. 500 words each. The process is you suggest an article title, I approve (or not), and you write it. Alternatively I can suggest a few ideas. Please **quote on 3 articles** initially. I may want more if your work is good. Note I'm not after spammy mass produced poorly written "SEO Content". This should be well written, informative, with a high level of English. If your English isn't 100% don't bother applying. Yes, it should have some consideration to SEO principles, but no mindless keyword stuffing. Please include 2 - 3 sample or links to samples of your writing with your application. **Not doing so will mean instant rejection of your application.**
