It all depends on what you're working with.
If you have zero $$ and beginner of skills to get started. For example working with sensual writer thumblogger and whatnot. You're probably not gonna do 10k per month.
If you have programming and design experience. Combined with a decent start up cost. It still might be a full time gig to make 10k a month.
No easy way in this fucking biz
I see people doing 10k + but they're buying traffic or they run big traffic sites.
