Recording in perfect English on green background

It is a simple job. I need someone who speaks perfectly Inglés preferably British and make HD video recording in approximately 40 seconds in front of a green canvas or panel, so I can edit the video later. The video will be used for an ad so you can not claim copyright. My budget is $ 20 negotiable, so please refrain those seeking a much higher payment. Proposals must Contain the word `Joker` at first so I know who Have Read the entire project. I need this in 2 days from when the contract is accepted.
