software development

Hi, we are needing a system which will work on a computer, mobile device and tablet, where employees clock into work on various sites using their mobile phones, computers, tablets etc. if they don’t have a device then the a manager must have a way to quickly clock in a large number of employees in within seconds on his device. The clock in system must have a gps location so we know for sure that they are clocking in at work and not at home. If the employee does not have data, the program must still log the gps of where the employee clocked in. We need it for android and iOS. We also need the clock in System to generate a timesheet for us to make it easy for us to upload it to our payroll system. Are you able to do this for us? We only need delivery within 30 days
