Ask HN: Why is it so hard to find a business partner?

Here's the short of it: I'm a good programmer with 10 years of experience. I have business ideas that I know I can build. I am not, however, a marketing guru, graphics designer, accountant, lawyer, or salesman. The problem is that I can't find anyone to go into business with. I can't find a marketing guru, graphics designer, accountant, lawyer, or salesman that's willing to take a chance on bootstrapping a project. I've gone to college students who claim to want to start a business, but at the end of the day they end up just playing computer games and drinking, and before you know it 2 months have passed and every week they give the same excuse: "I'll check it out tonight." To further emphasize this, I can think of ~8 people that I have actively engaged on various projects, and every one of them has flaked off and the opportunity has evaporated as the timing has passed. I don't know where else to look! I'm not in Silicon Valley. I have several ideas with a good monetization strategy that fill holes in their respective markets. I work on my ideas myself, but I know that execution (marketing, sales, strategy, etc.) are as important as the product itself, and those are the things that I am lacking. Any advice?
