Need Someone to Send Inbox Messages on YouTube who can start ASAP

Hello there, I have a company called www.minorsociety.com. We are currently in development stage, but will be a social media site for teaching and learning music on piano and guitar.

I am looking to target YouTube posters who have recently posted guitar and piano tutorials. I need a prewritten message sent out to these people from my account, and need proof that work was delivered. I am looking to contact 500-1000 targeted users. Who's up for the task?
