You want to do what is going to give you the most ROI (Return of Investment). Going this route will give you the results you are looking for at a much faster rate.
You have to ask yourself the following questions:
Would I rather spend the money now to leap into the next stage of my career where I actually belong?
Would I rather save a few hundred dollars and hope to get a few jobs that may help me pay for the solution that will actually solve my problem?
I don't know about you, but I would rather get something done efficiently the first time and be able to maximize my potential.
With that said, let's go over these solutions:
The "EASY" solution:
1. Pay someone to shoot professional scenes that show you in the best light, like Actors Screener Shoots. They will write you a professional scene, shoot HD footage of you acting the scene, and edit it. (Approximately a 1 week turn around with this company)
2. Acquire multiple scenes, but at least one HD scene and get them edited together at DemoReelsNYC. (Same-day turn around with this company)
Nice and easy, only two steps. Now.....
The "CHEAP" solution:
1. Have a friend or a cheap company shoot scenes for you. You won't have quality footage or sound, but once in a while some actors get away with it. (on average is in approximately a 6 month turn around between writing scenes, getting actors, and shooting it)
2. Edit the scenes together using a secondary cheap program. Editing can take up to 12 hours straight- and that's if you know the program well.
So yeah, its cheap. You will put in more man hours and be hoping the whole time casting directors do not notice that it isn't a professional quality.
And having "NO" solution:
Okay, obviously I'm not going to suggest this. Whenever I weigh this option I think to myself "If I continue on this path, where will I be in 5 years? 10 years? 15 Years?" If you have answered this yourself, you probably will not pick "no solution"
