The only way to bid on jobs is to purchase credits. The minimum you can purchase is $29.99. There is no guarantee that you will get work. After bidding on one job using the iphone app, I became unable to bid on subsequent job requests.
I responded to job requests within seconds of getting an alert on my phone and each and every time the bidding was closed. It is impossible that 5 people managed to bid before me within literally one second of receiving the alert.
I am unable to bid on job and unable to receive a refund from this scam of a company.
DO NOT WASTE YOUR TIME OR MONEY
