Python Call Blocker for Linux Phone

We need an experience python programmer to update and add feature to an existing Call Blocker application that runs on Maemo phone's (i.e. Nokia N900) The existing application can be found here : [login to view URL] (also attached to this project). We would like to see these features added to the application ; 1) ability to select a number from phone book; 2) show contact name instead of number if the entered number matches one of the contacts in the phonebook; 3) more choices for rejection, besides sending busy signal: silencing the call (and sending it to background) 4) ability to use wildcards, e.g. +40729* will match +40729000000 to +40729999999; 5) ability to block calls where the caller has no caller ID or withheld caller ID We require you to give some support to fix bugs after releasing this file +/- 30 days. This is a GNU project and we're going to distribute this software for free, so understand we don't have big budget. We do not have any problems to give you, the developer credit for this in the software.
