Here is a copy of the email I sent to email@example.com,
Hello there, I feel slightly impersonal as I have no name as to direct this email to.
To give a little about me I am student studying my second year degree in Visual Communications at the Arts Institute Bournemouth. I am currently searching for some work experience opportunities. The reason I approached you as a business, is the obvious need for photography to convey messages to the public. I have a keen interest in photography myself so contacting in hope that I may be able to act as a photographers assistant to gain some professional field work.
I'm currently working on my portfolio site, but I do have a flickr site which can be found here: http://www.flickr.com/photos/dhodson.
my phone number is: (+44)7933526611
Hope to hear back.
