Online jobs as data entry. Virtual assistants can make you earn money, but it is not very realistic to expect to earn your full time living doing these jobs online.
If you are really looking for a job online, you can find some legitimate ones on independent job sites. There are some independent sites where you have to pay some money to join, I do not recommend them. Most of these independent job sites protect the interest of freelancers like you by taking some precautionary money from companies that offer jobs. So that these companies can not deny you the payments.
