This type of ad is usually a start-up, MLM, or so where their investment is minimal and your investment is expected to be maximum.
Not that this isn' t the right thing for the right person, one just must know what one is getting themselves into- or not.
Movie/video making is like taking a 'self-starting' position without anyone, but you doing all the initial investing.
What I am trying to illustrate with words here is that there is money, rewards, and satisfaction to be made. What you need to do is realize that the investment will be yours, especially in the beginning. You will be the business end, the creative end, advertising end and all around end-ender.
Self-starting requires determination, positivity, stick-too-it-iv-ness and good old luck.
So, go for it! Be the self-starter you knew you could always be. Be the first in your neigbhorhood to asnwer your own made ad for a 'self-starter'!
Work for yourelf, but not by yourself-eventually!
You can start your video production as a hobby or career. Just be confident in yourself and others will follow- gladly.
