making 4 videos record----native English speaker only

I have 4 videos which created by myself which is teaching some skills about trade business. It's easy to be understood. But my English is Chinglish, which is not that comfortable for customers to watch the video. I want a person who speaks English perfectly to record the video again. I'll show my videos to you, you just need to repeat it with native English pronunciation. Each video is around 5 minutes, 4 videos in all. My budget is 24USD only. If it's not acceptable for you, pls don't bid. You‘ll need to send me a small demo which you created the video before. 1 or 2 minutes is ok.
