The idea is actually so simple, it would be difficult to turn it into a franchise or a quasi employment opportunity. The secret behind the business is What type of balloons to sell and which businesses to sell them to.
I read your about page and it looks like you would be privy to such a solution but I still think people really value branding, deliverables and personal training because of risk-aversion. If the idea is so simple, that's perfect. You could decorate it a bit and sell your support. Your experience selling balloons is probably much deeper than two sentence that share why type to sell and which businesses to sell to. And I'm sure you can think of a number of conveniences and types of support you would have valued in the beginning. And you don't have to share your secret upfront. You could probably get a down payment higher than $10 and then share.
Just because you wouldn't take the franchise or quasi employment opportunity (you've been doing small businesses since college!) doesn't mean the vast majority of people are like that.
I was hoping to actually create a brand out of a whole bunch of "easilydoable" ideas but even with this being my most successful idea, I am having so much trouble marketing it that it's truly frustrating.
