Its hard work in this business, and unless you either know a very unique and unsaturated language well dont expect any large income for the first 6 months or so. In English, well, it can take up to 18 months to start seeing real income.
We are very fortunate to move 99% of our efforts to the European market (mainly Scandinvian) about 3.5 years ago but I dont envy a new English targeting webmaster these days.
