Writer needed for product reviews - blog

It's becoming increasingly difficult for me to maintain my blog and keep writing affiliate product reviews and therefore i am looking for a service where someone can review a product and write an article ~ 450 words, once or twice a week

the process would work like this:

1. I would send you the product link
2. review it and write the article with keywords that I provide
3. send it to me and I will update my website with necessary links.

would this be possible, and if so how much would it cost?
it would also be helpful if you could send me a screenshot of the quality of work

thank you

note: seo friendly content is a must
