Blogging as a side gig.
Why not? Do you have spare time and would love to share your ideas? Be creative? You can set up a blog site…much like this one and include Ad Sense to make a bit of passive income.
You may also have a sponsor that will want to post there ready made ads on your site. This is where the really money is. While you have to change out the ads according to the time they want it on your site it really is easy money.
Pros: Good money
Cons: You might have to be a sales rep for a while till you build up your client-and-tell.
I will append some more articles on how to set up your blog and give you some good hosters to go with later this week.
