Determine electronic components needed for small Bluetooth device and micro usb port

The product is a cube shaped device that hangs on the neck, so it is small, like a necklace with low power Bluetooth connectivity to smart phones. The device will have two way communication with the smartphone, have a light source, and able to vibrate. We have already developed the server side software and mobile phone software that will communicate with this "cube". Need: 1) Components: a) battery - power - needs to be small, help us find best option that is small enough to fit in small device and last a few days. b) micro USB port for configuring and charging device c) vibrator so that the device vibrates on command d) Some visual colorful portion on the cube that lights up e) hardware/firmware communication with the smartphone via bluetooth and the micro usb port. f) Show source of the component and pricing A separate project will be CAD drawing of the cube to house these components. This project does not require that you create a prototype. If you win this project, you are 1st in line to get paid to create the prototype and continue working with us on future versions.
