Another thought to consider, are you able to offer a service of some type like ghost writing, article submission or
SEO?
If you have the skills, providing a service can be quite lucrative. And in the beginning you could get started just using your sig file to draw attention. Keep an eye out for people asking for service help, offer them a sample or freebie once to give them an idea of your ability and you could quickly make some money without spending a dime.
Some forums allow you to purchase an inexpensive ad, say as little as $20, which is another very inexpensive opportunity. When it comes to ghost writing, sheesh, if English is your 1st language and you have knowledge of specific niches...you are literally sitting on a gold mine!
Here is a crazy revelation about me, I have 25 plus years of residential construction experience both as an employee and business owner. While I have never ghost written in this niche, i could make a very good living just there...
...how about you? Where is your experience? You would be amazed at the amount of marketers out there looking for your knowledge!
