data entry typing jobs

has anyone tried one online and it works for you. I have a 10 month old and pregnant with my second. And my husband is about to leave the army and will be going to the police academy in the summer which he will be getting paid for once he starts his classes since he'll be working for a big city department. I just want to make extra money on the side. We moving into an apartment till he gets settle into the police force. And then going to look at a house for our growing family. That being said has anyone tried a typing online job or am I better off selling products online lol
