Manejo de redes sociales y campañas de publicidad para empresa de hosting

We're seeking for someone who can do social media and run campaigns for our hosting company. You need to understand about hosting + dedicated servers.
Good level of english is mandatory.

This is a long term / fixed position... We'll evaluate results based on monthly sales.

We can make changes to our site to enforce campaigns with promo codes or with whatever you think it'll be good to sell more.

Please do not post yourself if you're not confident that you can increase our sells.

We estimate few hours per week will do the job. Please quote your monthly rate.

The hosting company is from Argentina, but it's focusing on world-wide selling.
Please answer / ask whatever you want in english for our first contact.
Then we'll keep talking in spanish :)

Thanks!
