We have a clothing brand.
We want this clothing brand to be advertised on YouTube.
You would set up many YouTube accounts (real looking ones) and you would mention our link in reply to many many videos.
We would like it to be on over 1000 videos per day.
Please quote us based on one days work of 1000 videos, this would include comments on YouTube about the brand, from a real looking account, including the link to the site.
If you do the job well, this could be a daily job and earn a lot of money over a long period as we have many brands to do this with. The key is the real looking nature of the YouTube accounts (so people think it's a real person liking the brand) and the quality of comments which will attract people to the website.
