Comment Posting

Hello, We are a web company and our business is developing new profitable websites and products and buying already profitable websites to increase the revenue. For each of our website we have a SEO campaign that includes everything from article submission to comment posting. We are looking for a comment posting service to create quality back links by posting relevant high quality, unique and not spammy comments on relevant high quality, PR3+, DoFollow blogs. We are going to have at least several web projects annually so we are looking for a company or individual who can offer us a reasonable price and a good service with whom we can continue working for several years. We will give the keywords and URLs to different pages of our website and you are responsible to find the relevant blogs with PR3+ which are DoFollow for urls on their comment section. For our first posting campaign, for each of our keywords we want you to post comments following this schedule: Days 1 - 3: 15 comments Days 3 - 8: 15 comments Days 8 - 20: 25 comments Days 20 - 30: 55 comments This is for each of our keywords and we have 8 keywords, so we're going to have 800 comments total for our initial campaign. Then based on the result we initiate another campaign. We want slow commenting for SEO purposes, but let me know if you can handle several projects at the same time or you prefer to finish one and start another. When you complete this project, you will have to send me a report (Excel sheet) with the 800 comments URLs. Just keep this in consideration that we only pay for approved comments. Please let me know if you can help us with the above tasks and how much you charge for your service. Just take this into your consideration that we are going to have several projects annually so we are looking for a individual which can offer us a reasonable price and a good service that we can continue working with for a long time. We will always have different websites on different subjects. Since we're going to have so many projects and we would like to stick to one person, we are looking for a outstanding service and reasonable price. Thanks
