I used to run a magazine and can help you with advertising. My fee includes the expenses for creating and spreading advertisements for your magazine. I will make it so that advertisements reach a wide variety of consumers who are most likely to be interested in your magazine. If you don't already have banner ads, then I will have some created for you. I have connections to a web/graphic designer who has always made ads for me in the past and can whip up several ads for use.
There are going to be a few things I would need for you to do to make this advertising campaign as successful as possible. At the end of the 15 days, once I have the advertising campaigns up and running, I will hand over all of the accounts I've opened to create ads for your magazine so that you can continue the ad campaigns on your own. Once I've set it up, it should be very easy to do, but I'll be happy to tell you anything you'll need to know to keep your campaign running at its best.
