There are sites out there for data entry. You search and collect data and upload that data. Unfortunately a site like CrowdFlower looks promising but it is all about casinos and the only way to make money in a casino is to own one. They have good remarks though in Forbes or The Washington Post.
Megatypers.com looks interesting however there is no About Us, no Contact Us on the site. It just does not write who they are. You need an Invitation Code but nothing on the site writes where to get one from. Searching wil show you invitation codes but what does it mean? Avoid them and look for better data entry companies. If you are still keen and have an invitation code and hopefully for you it is not scam then try out your luck. But a website that is not writing who they are, where they are or how to contact them is a website to avoid.
A really big site to make some valuable money is Amazon Mechanical Turk and work on HITS. There are quite a lot of hits and then you have to think in the range of watching a Youtube video and answer some questions to listening audio fragments and put that on "paper". It is the marketplace for online work and there will be enough work for you. Some tasks only will earn you pennies but once you become a big HITTER then tasks go up to over $50 and that is not bad for home work isn't it?
