I don't think I'd count on arise.com since I couldn't even get their website to come up.

The other one seems to have a sense of legitimacy. In reading their FAQ's they pretty much give you an idea of what goes on and they stress that it never costs you any money to apply or work for them...that's a good sign. Given there's no cost involved I'd say if you like talking on the phone...give it a try, nothing to lose but a little time.
Good luck
