Professional voicemail for Skype number

Hello, I need you to register a voicemail in English for our Skype number that sounds professional. I will send you the login of our skype account so you can record it directly. The script for the voicemail will be something like the one below. ------------ Hello and thank you for calling OA Advertising. Our business hours are 9am to 5pm Monday to Friday. Please hold while I am connecting you to one of our agents. (Here make ring artificially for 30 seconds or play a waiting music). All our agents are currently busy assisting others. Please try again later or leave us a message after the tone with your name, phone number, email address and we will get back to you as soon as possible. Thank You. ------------ I need a woman voice for this, native american or which sounds like. Please attach a sample of your voice with your bid. The script should totally take around 45 and 50 seconds. Thank You
