British English voice-over for tutorial video

It should be a British male voice with RP (Received Pronunciation) English or Standard English accent. Actually this sound is for some tutorial video. But you don't have to synchronize your speech with the video. I'll do this myself using my sound editor. There is about 5 pages (2350 words) of the text. The sound should fit into 19 minutes or less. Also if you make any mistakes recording the sound, you don't have to begin from the start. Just record this phrase (or sentence) as separate file. It is possible to use any standard sound recording software which is available in Windows, Macintosh or any other OS. File format is '*.wav', 44.1 kHz, 16 bit, Mono. The tutorial video (at the moment it is in other language) is available here (just in case): [login to view URL] Please provide your voice sample by reading the first paragraph (25 words) of the text.
