I'm currently running a blog that has been picking up in terms of web traffic. I'd like to start expanding my reach into other niches but I would need other writers. I can't afford to employ a team so my idea was to have independent writers pitch content to me and then pay them a percentage of the ad revenue for the day(s) that their work was featured. My question is would I have to register as a business to do this? Or deal with any tax stuff? I can't imagine I'll be making more than $10 a day in terms of revenue -- at least from the get go.
