Regards, this is a great project, so you need an equal person for this job.
I am familiar with social networks and, of course, with their influencers, so I can say that I know this field very well. But, of course, you need someone who can sell (in this case, a service) and I'm good at sales.
Of course you need someone who can manage english as native because the job is calling enterprises and sell our services, that won't be a problem at all, i know it since i was a kid.
I don't have to say that i'm responsable and very proactive so i can work a lot of hours.
I don't want to extend this proposal much, thank you for taking the time to read this and if you have any questions for me, i'm available, thanks.
