Design and build both an Andoird and iOS mobile Bluetooth application.

I am busy with a project that controls electronic hardware and is in need of someone to design and develop me a mobile phone application that will be used to control my electronics (controller) via a classic Bluetooth connection. The application will pair itself with the controller in a similar way as how a mobile phone pair with a car radio. Once paired the user can set / get various parameters on the controller via the Bluetooth interface. The application also has a Facebook / twitter message upload facility to upload messages such as "look guys, I am here", using the GPS position. The app will have a couple of buttons with pre-set values assigned to them. When the button is pressed, the data will be sent to the controller, the controller will acknowledge the message. Once the acknowledgement is received will the button on the mobile app indicate that that specific setting is selected. The app will have between 3 and 5 pages. One of the pages will have two sliders. The slider value will be sent to the controller and acknowledge in a similar ways as the buttons. The status of the Bluetooth connection shall be shown at all times. The right person to do the job should be good at: 1) Designing UI / UX / Graphics 2) Have experience with Bluetooth connections 3) Have a number of sample project to show me 4) The app must have a professional look and feel. Once done, the project must be made available on the platform app store. The source code and all the related files must be handed over to me and I must be able to compile it on my own machine. I will require your assistance with it. This is the initial version of the application. There will be more releases and I am hoping to use the same developer for future releases. I will provide detail information at a later stage. When you contact me, please provide me with samples of applications, note that they MUST have Bluetooth connectivity in them. I will not respond to messages without samples.
