I know this is an older post, but I'm going to share a really cool tool that I found to help me find a good video company. It's called Video Pixie, and you post your job on it and your funding range, and you'll get quotes from some great video creation companies. I found it very worthwhile!
https://www.videopixie.com.
For example, I asked one of the companies - how do you find the right actors for the video? They said "We're in LA, and we use
www.LAcasting.com and typically get 1,000 responses, I narrow that down to the Top 50 and share that with you and we then pick the ones we want"
I then asked how he finds the right place to shoot the video. He said "I use
www.peerspace.com which has houses that can be rented by the hour or by the day".
Amazing!
