Letter of acceptance to be filmed

I have sent an email to a girl I'd like to act as the 'star' in my video. I've chosen to have one person acting the narrative and to be the singer. Giving a more personal feel to the video as the song has a very personal subject. The letter reads:

Hi Olivia,

I'd like to ask if you'd take part in my A-level media coursework where I'm making a music promo including a music video, magazine advert and digi-pack. I'd like you to act as the artist throughout these 3 tasks. This involves you taking part in the music video and also feature in the ad and digi-pack.

Thanks very much for your time
Laura

The reply I received:

Hi Laura,

I would be delighted in taking part in your A-level media coursework.

No problem,

Olivia
