Native English with American or New Zealand Accent Voiceover for Tutorial Video -- 2

Hello, I need a female American or New Zealand accent voice over for a telephone tutorial video. I'm opening it up to both type of accents as I am not sure what my client will want at this stage. Here is an example of what is being created: [login to view URL] If you have worked on similar projects before, please provide links to your work. The video has 17 segments, with roughly 3900 words total in the draft script. I estimate the video will be between 25 - 30mins. There are 4 other similar videos that need to be created in this project so further work is guaranteed for the right person. We also have other training videos projects so we are looking to build a long term professional relationship. We a need professional, corporate sounding voice that is also sounds interested in what they are talking about. We have a detailed script to follow but you will need to be able to re-recording segments if needed. You will provide 2 free samples before the work is started and be able to edit your work. We may need you to supply royalty free music, this is unknown at this time. If you DO NOT have samples of performing this similar type of work before, please do not send a proposal. Thank you.
