LUA programming on freeswitch

We are using FusionPBX, in which, we want to play a IVR, which will be an announcement like: hello engineer, your site id: 12345 is down since 10:25 am, please reach to the site with address, 12 pavel street delhi. the severity is, 1, and priority of the issue is, 2. The numbers are coming from a data source every time announcement is played. this is done in fusionpbx/freeswitch using LUA code; as we have learnt. We need someone to write this code and give this functionality.
