Facebook AutoPoster Application/ software

Hey All.. I am looking for an application developer.. who can make a facebook friendly application in reasonable price. and what i need is an application which can autopost on facebook in my friends wall as well as in groups and facebook pages ... This application can be desktop or some internet web script... but is should be 100 and 10% working... you should be tricky and a playboy with facebook tips and tricks... My tool should be facebook friendly or clever enough to not be caught... kind regards
