I have a nearly completed an Android VOIP calling app that changes the user's voice while he/she is calling.
It has the following features:
1. Refer a friend: DONE
2. VOIP aspect (Twilio coding): DONE
3. Voice changing code: DONE
4. In-app purchases: DONE
5. Integration of VOIP code and voice changing code: NOT DONE

So it is the last part that remains not done because the coder now says he is too busy and does not have the skills.
It is overdue now and I am looking for a highly skilled coder who can do it right and within a week.
