To use the Mob4Hire service, developers would post their project details on our site and specify the handsets and networks that they would like to test on. Additional information would include an estimate of time involved and the size of the download, if any. Mob4hire sends an invitation to bid to those testers that meet the criteria and the bids are placed. The developer decides which bids he/she want to accept, if any. The tests are completed and the funds are held for 5 days so the developer can ascertain quality. All testers and developers are rated after each test and all payments are made through PayPal and Mob4Hire retains a commission.
