If you can write well there are a lot of people looking for content writers. You can do a google for
content writers and find a lot of places to start looking.
A lot of people try making money on ebay. There are a couple angles there. One is to find items listed in the wrong category, buy it cheap, and then relist it yourself in the right place. The other is to find a niche and resell. There's a good market in used business equipment and not just computers. Scaffold, nailers, copy machines, toner, etc. The business people won't care about paying for UPS where the individuals expect to pay $2.00 for something, and have it include the $8.95 in cartage fees.
