I am a professional writer with a degree (BSc, Hons) in biology and experience working with pets - I lived on a farm and worked in a pet store. I also have a number of cats and dogs and I run a small pet sitting business in California.
I will do the first article for free so that you can confirm my ability. After that I will write the remaining articles, error free, asap. Realistically, this will probably take over a day, but if I can do it in less, I will.
I also guarantee the quality of my work - if you find any errors I will correct it and give you that article for free. Thankfully, this is very unlikely to happen as I have been writing for a long time.
