I am looking for someone to install A2Billing onto a fresh Asterisk server for the purpose of call conferencing.
Initially I want users to be able to purchase pre-paid credit and book conference rooms from the web GUI.
In the future I will be looking for ongoing maintenance and customization of the site.
Easy job! I could get it done for you right now. I develop web applications on the platform of LAMP (Linux, Apache, MySQL and PHP) for many years. If you are looking for a professional developer, please feel free to contact me. Thank you.
