Progress problems

I am still finding it hard to find people to be in my video because of where and when I need to film it. This leads to me still not having started filming yet which is a major issue. To solve this problem I have to decide whether to change my ideas for the video, but I'm lost on ideas for the song I'm doing other than what I have already planned.  This has lead to lots of difficulties, because it is unlikely that I will be able to find people to be in the video at the time and requirements I need to achieve it and have no ideas on how to change it. One option I see is that I have an idea for a different song in which I would be able to film more quickly and easily. I don't see a problem with changing my idea because I haven't been able to begin filming for the original idea, but I have yet to discuss this with Miss Hill.
