408023 Post 500 youtube comments

I need someone who can post a comment to 500 videos that are the results for a certain search term. The comments must be adveritisng my website/ebook. For example, if the word was "Dog Training" you would post a comment on the first 500 results for "dog training". The posts could be something like: "Nice video, but I prefer the stuff at mydogtraining-dot-com." or "If you like this you should google the My Dogtraining website" etc. You must provide a log of which videos you have commented on and the comments must be visible to me when I check the log. You need to post them in such a way that they don't get deleted by youtube. Thanks
