Blog commenter/Link builder needed

What you have to do is post comments on blogs/pages/url's (we'll provide). For name,email and website you have to use what we'll provide and in comments you have to put relevant comments so blog owner doesn't mark them spam and allow our comment to appear on there sites. Looking for white hat methods only. Will need an excel file showing what sites you posted to, along with username/pass if site requires one. Please reply with examples of your past experience, methods you will use for link building, timeframe that you will be available and cost per hour. If your prices are low then i can hire you for full time(8 hrs.) For now it's for 4 hrs. a week. Regards Dino
