@Tania_small_tits, ModelCentro is primarily a CMS, and you in fact do become a webmaster of your website - without having to pay for design, hosting, content storage etc. - It's made for websites exactly like the one you want, so please do take a look at it and try it out, I think it fits you really well.
We also have a great knowledge base and discussion on promotion opportunities in the MC community
