Define a lot since it is not specific, and can vary from person to person. In my opinion making $1,000 dollars a month would be a lot. Due to it being hard to find jobs now days. Making that amount of money is possible you combined with Adsense, the ads on Hubpages, and amazon/eBay affiliate programs. But with just the regular adverts you would need about 900,000 views to 1,000,000 views a month. It can be done however it would require a lot of work to achieve that kind of earnings.
