They invite you to post a job for free. However, you cannot send or receive messages from caregivers, unless you pay - and there are different levels of paying - to receive and send more messages or "quality" messages = more money. Stay away from this kind of site completely. In an age of AirBnb and uber, this kind of site and payment scheme is obsolete and harmful - espcially when considering they are representing "CARE" givers.
