Need an android App

Team,
I need a android app.
what It basically do is the function of a Phone Book application
but before giving it to users it should be customizable with needed logo and image
There should be a way for Bulk addition of contacts into it...

Primarily when the user gets this app it will be a phone book
pre loaded with contact numbers i have loaded

i may frequently update..the app with contact numbers or change the image as i need..

Is there any way of doing it...i am looking only for a free ware option...

Have no idea how this can be done...All suggestions welcomed

Thanks mate for prompt reply...How much this gonna cost but....i find apps starting from INR 100
