hi,
i own couple of websites and plenty of blogs, and i have a team of writers & we provide article writing, web-managing, re-writing services to 7 of our clients based in US, UK, Oman, Spain, Portugal, Amsterdam and India! I can get the job done pretty easily, because i know what kind of comments you would be looking for.. But i am just confused about 1 thing.. You need comments of 500words???? please clarify and furnish me further details.. I will tell you specifics of my website, so that you may refer to the effectiveness of my previous works.. Many of my articles are on top of Google listing!
- hope to hear from you soon!
