Require professional content for service pages of a website

Hello,
I require professional content for the service pages of an IT business website. The writer must have excellent written English skills and grammar usage. The content needs to be optimized based on keywords and must be 100% plagiarism-free.
There are around 6 service pages, each page requiring an average of 700-800 words.
It will be much appreciated if the content writer can give us valuable inputs/suggestions or constructive feedback on how to improve and optimize the existing content on the website as well. I prefer a content writer who is open and passionate about his or her work and enjoys working within a team- collaborating and sharing ideas for improvement.
I am only looking for highly experienced professionals. Please share your portfolio along with your proposal. Please mention "I am ready to work" in the first line of your proposal. Any generic or copy-paste proposals will be straight away rejected.
Looking forward to your proposals. Thank you and have a great day.
