I see you have:
Twitter:
https://twitter.com/sexyJenySmith
Instagram:
https://instagram.com/sexyjenysmith/
I would also add Tumblr:
https://www.tumblr.com (and link it like with twitter to your ModelCentro site).
Next build these 3 sites up.
Instagram is easy. The simple thing to do is find models with your look on Instagram and go follow there followers. You can only do so many per hour, so you will have to keep going back. Do not post nude pics on Instagram as its not allowed.
Do the same for twitter and Tumblr. Tumblr only lets you follow up to 200 a day. Be carfull of following too many at one go on twitter as you may get your account banned.
