has anyone joined any sites that you can post resumes at and really gotten a job

I've posted my resume on some job sites, gofreelance,careersearch,etc. and so far i Haven't received any response. I just get plenty of offers to start my own business( i don't really want to do that),plus to get the information you have to pay 40 and up for the informaton kit. I've tried paying surveys,I just joined odesk it's where you can sign up as a freelancer and apply for jobs. Hopefully, you can a job interview and maybe they'll hire you. I want to earn some extra money working at home so I can take care of my daughter in the summer vacation time,because i want to be at home with her. Her dad works full time but we can use the extra as i'm sure everyone buying food,gas or heating fuel knows.
