shashank, you will see regular SEO suggestions everywhere like post on blogs, forums and so on. Seeing your domain, I can suggest you a wonderful idea.
Ask all your models to create their personal websites from any web designing company be it a new domain (better) or free personal blog websites through various blogging websites and then ask for a simple backlink to your your website. As and when they will improve their websites, your website will improve automatically. If they get their websites designed preferably by an SEO company like PlaceOnTop.com which is in Delhi itself, it is even better because the seo company will increase the value of the back link to you.
