I will record your IVR telephone on hold messages

I am a professional voice-over artist. 

I worked as a professional radio broadcaster for 6+ years on a variety of commercial stations. 
My voice has featured in videos and adverts for blue chip firms.

I will record your telephone on hold messages/IVR

I recommend NOT using background music. 
Why?
Because
the current style is clean and crisp with no music,
also GSM phones - which you callers will likely be calling from - cannot compress music properly.
In addition, music dates quickly. You will get longer from clean crisp messages.
