Mobile -- 2

I need an Android app. I would like it designed and built. I also need an I phone app they will both do the same thing. I need my clients or potential clients when they need my service they can go to the app and click request service status of service request. they will enter their name company name address and zip code for service and call back number and budget rate for service. once they click send the service request goes to the sales team that has the app on their phones so they can see all requests for service they cam then respond back with the rate for the service and a button to confirm to and agree to rate please book and schedule the [login to view URL] app would also need to he setup for the subcontractor to get his alerts and to take the job the subcontractor and employee can almost be the same. the app would then be in subcontract device and the sales team would send job out to all subcontractors within a 20 mile radius the app will identify and know via GPS. zip codes area codes of all companies and subs within a certain geographical area. the subcontractors can bid on the jobs too that are sent out. then the sub control or its employees can then send have a button that sends message to original client letting them know the employees staff location. they can hit I'm on my way. I'm en route and will show their locations to the cleint via the app push notifications. the app would keep track and file all calls requests for service locations and then act as a tone clock for the employee subcontractor clocking and and out if each location worked and required to send an alert via the app every 3pm minutes or hour to signal his presence at the location gps. I am looking for an expert in this field this isn't a simple app but it is. there are already similar apps put there so may be a Metter of using that code if it is shared and open sourced of course to help Jumpstart the project. I can direct you to similar apps. outs just needs to be customized. I'd the work relationship is good dynamic and good work person dedicated and committed to this project is may consider bringing then over to the USA on work visa to help with this project. we will need long term support and help. we are looking to make multiple apps similar. so the person that helps us the most in the beginning stages will be taken care of. we appreciate your help and please be able to do iPhone and Android and be beyond good
