I am looking for a very good coder to create an android app for sending bulk sms's.
the user should have the possiblity to do the following actions:
1.- Select all contacts
2.- Create a Broadcast-List ( Edit/Add/Delete contacts actions)
3.- Set a pause-time-intervall to avoid blacklisting of the SIM-Card
4.- show a Progressbar of the sending-action
6.- Multilanguage Support.
Please only bid if you can provide samples from your previous work
