Hi suppose if you do free online jobs, you can gain little more profit and almost all them are scammers. So better you can go for paid online jobs. I would recommended one of the legit online job that is reselling business.
Reselling business means you can just buy a website which contains Domain Registration plans,Hosting Plans,website builder,E-mail Marketing etc.. from a reseller for a particular amount and you can fix your price for that products and you can market it and gain more profit.I registered and got an account in http://www.goresellers.com/
.I just have sold domains hosting plans at a higher price and gain more profit. You can also get the account from this site and gain more money.
