Steve made excellent points.
I’ve worked consulting an inventors group in my home town and this is a very common dilemma.
I always point out that this is not just a decision about selling through the channels you’ve mentioned vs. manufacturing it yourself. If you go on your own you’re really starting a business and you must think of all of the business issues, not just manufacturing.
Another issue – selling thru Oprah, QVC, etc. is not generally a sustainable model. It’s more a 15 seconds of fame kind of thing.
If wealth creation is important to you, building a business around your idea is really the only sustainable path.
I agree. Many inventors usually can support themselves financially starting off. It is easier to do video presentation on a website, and do some viral marketing. After selling a large amount of the product, they could do local commercials. If someone sees it as a great investment, they will take it nationwide, and give you a larger piece of the pie.
