Need custom green screen footage

I need this on the cheap (around $50) as I am currently unemployed, so if you're not feeling generous, please don't respond.

I am trying to get a home business up and running and I'm working on my logo. I have purchased the following image from Dreamstime:

What I am looking for is green screen footage of a camera by itself and then a man moving into frame and bending over to look through the viewfinder. The final frames should look almost exactly like the logo above.

I don't care about lighting, I'm gonna key out the green, turn the remainder into a black silhouette and freeze the final frame, which I'll end up using as part of my logo in place of the dreamstime image.

Please send me a private message if you can help.

Thanks!!
