Backlink Builder/Poster

I am looking for someone who can post intelligent comments with back links to my website on different sites such as digg, web design blogs, template design, graphic design and related sites and/or blogs. On my website I offer paid and free templates so comments should be related to my content and on related websites. The comments should be on websites that have Alexa ranking 20,000 or lower. You must have good writing and grammar skills and MUST know what you are talking about when you are posting comments. All posts must be in English so I can read, understand and approve them. If a comment is ridiculously bad or on a completely unrelated website I will NOT pay for it. If your posted comments are deleted or removed from the target website I will NOT pay for it. If you use common sense when posting comments there will be no problem. The bottom line: - This project is about back link building for my website through posting sensible INTELLIGENT comments on web design related websites. - I am looking for 300 comments and back links. I will do more if you can produce good comments on good websites. - You must produce and share a Google Spreadsheet with me and update it whenever you post a new comment on a website so I can monitor your progress. - The sites or blogs must have Alexa ranking 20,000 or lower - I will NOT PAY for non-nonsensical comments To be considered for this project: A) *** Please send SAMPLES of your previous work, about 10-15 comments made by YOU on 5-10 different blogs or websites *** B) How much you charge C) How many intelligent comments can you post in a day? If you have any questions....you know what to do.
