Freelance help on new project

I am building a new project and new to Arduino but know the capabilities of it. This project in basic form will measure 1 -3 pressure sensors. And via an app on android the user can increase or decrerase the pressure via outputs controling soleniods. The app will display current pressure and a level for the user to change. The app will also set the upper and lower settings for the pressure. I have a system using a pic and other hardware I have designed myself, but I would like this to go further. This is very basic at this time, but if interested in coming on board a more detailed explantion will be forthcoming. I reside in Australia, fyi. Anyone interested or know anyone or can point me in the right direction will be greatly obliged. John
