estimate and sell a website or continue

I make my first site. This is a porn tube of about 1500 videos with a blog and an affiliation with a group of cams, turning on a vps the design is simple and clean. Only now I ask myself questions I do not know how to make it known, I do not know how to use social networks, if I sell it how much I can have, if I continue, what strategy to choose. I am French and speak very little English. If someone can estimate me the site, finally to have traffic early how to do it, thank you in advance
