Identify An Employer/ Company That I Can Invite To The Degree Show

Unfortunately I found this task very difficult as I have no connections in the industry. I have emailed companies before regarding work experience and work after my course and have failed to get a reply. Despite this there was still no harm trying, so I thought that I would aim to invite a company that I would like to work for after I have completed my course. I emailed the London visual effects company Double Negative. Below is an image of the email that I sent.

Unfortunately as I expected I have not had a reply yet. However as it has only been a few days I still remain positive that I will hear from them soon! I was hoping that Double Negative would give me the contact details of someone within the company that would be interested in attending the degree show so that I can email them. Once I have got a verdict as to whether they wish to attend or not I will then inform the degree show team so that they can send them an official invite. Which will look more professional than a email from me. I believe that the degree show team also want to know who we have asked so that they can keep track of who has been invited, this will prevent the same person being invited several times.
