Eimimo is the site I was happily to introduce to my followers as it promised to offer a lucrative $10 upon registration, and every time you refer a new member, you get paid 25 cents according to its site statement. I have referred hundreds of members to this site and I was happy about that. The only drawback of this site is the requirement to read $5 worth of emails yourself before you can ask for any payment, and it took me one and half year to read enough emails to accummulate $4.
Become a babysitter if you are good with children. There are websites that will connect you with people who need a babysitter. To get hired by people who do not know you, it will help to pass a CPR class, or to have a special talent or expertise for entertaining children. However, you might be able to make money more quickly just by babysitting for people you know, or by having friends refer you to others who need a babysitter.
