I am a freelancer looking to support as many people as possible and of course this includes myself and my family.
I don't mind doing this project for you for free if I will get a genuine review from you to boost my reputation as I can assure you I will do a good job.
As I understand the project you need someone to create mp3 voice recordings which will be used to welcome calling customers to your phone system and also to tell them they are being put in a call que. That is two separate audio files.
I intend to achieve this using NGWave recording software, my computer and a headset with an inbuilt microphone.
You may contact me for further details/clarification.
