Assist me with Bulk Marketing

I have approximately 1350 social media pages that I would like to make contact with in the next 1-2 weeks, and I need someone to send out a series of messages to them. I would prefer that each of the pages be contacted via a personal message whenever possible (on Facebook), but if not available (Twitter and YouTube), then I would prefer for them to be contacted through a comment on their page. The accounts used to send out the messages should appear to be from the USA. I will supply social media urls and the messages/comments to be used in a spreadsheet. In the spreadsheet, I will need you to fill in the link to the message that you sent (if possible), as well as a copy of any reply made by the page owner. I plan on messaging the same accounts at least two more times after this initial engagement, so there could be more work for you, if the job is completed successfully.
