This depends, like most things, on how much work you are prepared to put in. Any business start up comes with risk. An established 48 page magazine that is filling its’ advertising capacity can bring in approximately $4,000 a month in net profit from magazine advertising sales. Technology sales can add approximately anywhere from $1,000 in month one to $7,000 a month after the first year of operation. Please see the Potential Earnings sheet for more details.
