find a few clients (small agencies) looking to make their operations more efficient and become a freelance media buyer. In order to do this you will need to start as a media buying assistant at an adv. agency or work in media sales to get started. As an independent, in order to offer a service you will need to learn the trade and have some kind of reputation to back it up. I have a consistant six figure income while working from home giving me tons of time with my family which is more important than anything. One of my clients requires a visit once a week from 9a-2p in order to maintain a strong face to face working relationship and process media invoices, but other than that the computer and phone are your best friends. Otherwise working for a big agency will top out at around 55k per year, unless you advance to a media director which at a select few high end shops you can garnish a low six figure income...but to get there you will need to be 'top in field' and have over 10yrs exp. and work some high stress hours.
