Looking for someone to write blogs on my website regularly.

I have a coupons and deals website. It provides customers with coupon codes, promotions and discounts to save money while shopping.

I am looking for someone to write blogs for this website regularly - Maybe once a week. Need someone who can commit to write on a long term basis.The blogs can be around 100-150 words. Sometimes it can be just a short paragraph.

My main focus is to find someone who has ability to write good English language/grammer and is creative in their writing, has a friendly tone in their writing. This website mainly focuses on US customers and so someone who has knowledge about US shopping trends/festivals/holidays/seasons will be ideal. I would like to proof read any blog before it gets submitted on my website ,so someone open to minor editing based on any questions/thoughts I may have would be good.

Thanks,Mini
