Schema, design and Arduino device & software for driving metrics

Dear Arduino expert, I am looking for the talented Arduino-specialist, who can combine different kind of Arduino sensors together in the way, that at the end there are fully working Arduino design and software inside device. REQUIREMENTS: a) Freelancer needs to be able to communicate in proper manner and give frequent updates how project is going on. b) Freelancer needs to provide list of hardware at the beginning of the project, so that while freelancer is building Arduino project, we can order the similar setup of hardware and sensors and we can build the duplicate system. c) Freelancer will provide list of all hardwares, sensors etc. and short instructions how those should be built d) Freelancer will provide both binary and source code from the software with documentation so that software and hardware combination can be tested and also source code is reviewed. e) Freelancer doesn't need to create server side nor server side code. The data is uploaded frequently to the cloud based service via JSON API. JSON API syntax is easy and interface clear. PROJECT SCOPE Design and build hardware from Arduino based devices and sensors: System will include motherboard, box, gyro, GPS-sensor, GPRS/mobile data accessory, three different kind of led lights and power on/power off button. Idea is, that when car is starting to move, then driver press button to activate device. First led light tells, system is on. Second led light tells that GPS Sensor has connection to location based tracking and 3rd led tells that mobile network for data transfer is available. The metrics box will store locally driving data, including (once per second) speed, acceleration, location and time (cumulative) how long the car has been moving (or device has been on). The timed action is taken place, when system will connect to the cloud based API and transfer data from client to server. Identification is done my SIM-card or same kind of identification method). When user turns off the power, the system tries (few times) send driving log to the server. if not possible, stores data to the device. - The device does not have display - Device power is provided by USB (car lightener plug-in) SUCCESSFULL PROJECT We are able to build the similar kind of driving log collecting device and able to use that in real car. System tracks different kind of driving metrics and uploads those from device to cloud based system. More detailed information is provided when requested to most promising Arduino engineers/developers. Happy Bidding! Best Regards, Hanttila + team
