British English Narrator for Vocabulary

Hello, we are a small eLearning company. We are looking for a professional speaker (British English) for a Business English quiz. In the quiz the English vocabulary should be spoken to support learning. The text is about 176 lines, each line only one or a few words of vocabulary. There should be only a very short pause between the lines, maybe half a second. The text altogether should take not longer than 3 or 4 minutes to speak. We need one sound file (wav or mp3 in high quality) with all of the words spoken. The text should be recorded in high quality. If you can provide a sample file with your recorded voice that would be great. Here are the first few lines of the text: asset company constituted under civil law constitution enterprise entrepreneur general partnership joint-stock company public limited company entity liability Thank you, best regards, Michael
