I can help.
As a professional sports broadcaster and voice over artist for one of EA Sports most noted games, I have recorded countless items from soft spoken commercials right through to knock 'em out of the park spots that have people itching to get out to a sporting event.
I will prepare a professional sounding :30 second voice greeting in an .mp3 format that you can use for your voice messaging. All I need is a script of what you want it to say (no swearing or derogatory remarks - reviewed at my discretion) - and within 48 hours you will have it emailed to you ready to use.
This is an awesome way to catch people's attention and let them know you either 'mean business' or have a 'silly side'. For those with sports fans in the family - this is an incredible deal!
