Earlier quoted context omitted.
Yes, they are real jobs. But you have to make sure that it is from primary vendors. Often times, many secondary vendors source for the same job listed by primary vendor. One way to cut down secondary vendors, ask for decent rates. If someone asks you to work for $60 per hr, just say NO. Even primary vendors have outsourced their recruiting to India.
$60 per hour isn't a decent rate?
$60/hr as a contractor is the equivalent of $30/hr or less salaried. At $60/hr, it's probably even less than $30/hr because you are not eligible for ACA tax breaks and must pay full price for health insurance. The health insurance plans available on the individual market have large premiums and deductibles compared to plans that employers subsidize. You also have a larger tax burden, including the need to file quarterly.
The rule of thumb for contracting is to take your salaried rate and double it at minimum.
