Yes, sign up with may companies, that will give you more options to chose from. Open Paypal account, that's how most of companies pay, it is convenient and safe. Read instructions, print them out and read them over, with time you will know it by heart. Yes, do not flake! If you say you will do the shop, do it! And if something unexpected comes up and you cannot do it, let your scheduler know asap, maybe try to reschedule. You have many companies....A-Closer-Look, Coyle Hospitality, International Service Check, Sentry Marketing, Bare International, etc. Good luck!
