We need a marketing Guru

We need a marketing Guru, a good hand at digital marketing too, in order to get artists/celebrities/athlete etc on board Motion to sell their videos. Sending out invitations to their emails, facebook, Insta, tictok, YouTube, phone calls if needs really. We will ask/tell the creators to give 1 or even 3 videos out for free which they can also use as samples on their profile page(we use this as an excuse maybe lol). Then we can use it as a promotion to get users to get those limited free video requests on first come first serve basis. Can be such a good promotion We will have to include the clause of a free video in the contract or even when they sign up. Can even make a free video voluntary like ticking a box while signing.
