Adsense is too low of a payout for me, I always have adsense + offers on my pages.. but there are many ways to do it..
i think it is time , the more time u use corretly to promote your site the more he can delivers , and off corse a server who is not going down after 10 visits
I can suggest you to start with your site and do something you're familiar! I mean if like football - to sell football stuff and so on...
