Leave posts and forum comments for health related blogs and forums

Hi you will need to search the web for natural - holistic and alternative healing blogs, forums..mainly in the UK and the US but also worldwide. You will need to leave 4 different comment with pictures if possible on each sites. I would like to you find popular ones with many visitors. So you should think in areas such as medical sites, alternative healing sites, unconventional medicine or healing, holistic healing, crystal healing, blogs of big health magazines, tv -radio stations, You could use key words such as holistic, health, holistic healing, natural health, alternative healing, fairtrading, barter, crystals, aromatherapy, essencial oils, clinic, centre etc... Facebook and Twitter accounts would be also excellent. Please apply with a few sample, which you think would be suitable for what I am thinking about. And please also mention how many hours would you need to find 40 different sites and copy paste the 4 different types of comments, over 1 week period of time. I will choose more candidates for this job and I will first consider those can do it within a few hours. I will be needing this project in the future at least once a month. Thank you I look forward to hearing from you. I understood it is an easy job, so I will go for the one who can deliver within a few hours work.
