well, I'm a nerd pretending to be a business guy, not the other way around, but I think some of the same lessons apply.
First nobody will take you seriously (as a business guy or a nerd) without some experience. so we need to get you some experience.
Do you have cash? if not, go get a regular job. get it the way regular business grads do it (what I mean, is you need cash for the first step. not a lot of cash, but some. a job, in my experience, is the easiest way to get cash. If the job sounds impressive, it can also count some towards experience. But, if you have enough cash already, you can move on to step two.)
Now, find someone to hire. You can hire inexperienced nerds for very little. depending on where you are, anywhere from min. wage to $15/hr will get you started. Note, you won't get anyone with experience for this rate... but sometimes you get really promising people without that attribute (and you can't afford experience right now, unless you have more money than I think.)
the thing to remember here is that you will probably end up firing the guy. I mean, I know nerds fairly well, and I end up making a lot of mistakes, so you will too. The trick here (and if you can learn this, you will have vastly improved your value as a business person) is to learn how to fire well.
By firing well, I mean you need to learn how to get rid of your mistake without making an enemy or making him or her feel to bad. It's a small community and if you have a rep. as an asshole, you are going to have a hard time picking up your second guy. (and when you find someone you don't need to fire? be /extra careful/ - that guy's friends will be the people you want to hire when he moves on to a higher paying job... or he might be the co-founder you want.)
I think the key is to start people off as contractors without the expectation of continued work. If they don't work out, you pay them for what they did, and the job is over. Nobody's expectations have been violated; nobody feels ripped off, etc... Only move someone into an expectation of longer term employment once they've proven themselves. As you get better you can move on to figuring out how to fire people who have been working for you for a while... but that's pretty rare if you work everyone as contractors first. People will leave, but usually they leave on their own for more money before needing to be pushed.
next, if you do manage to do something cool, always give the nerd who helped a bunch of the technical credit when you are talking to other people. It'll make the guy feel good, and if anything, it makes you look better. Nobody likes (or believes) a business guy who tries to takes all the credit, and really, as a business guy, if you pick the right nerd co-founder, that makes you look really good. by pointing out how good your nerd is, you are pointing out how good you are to have found and kept that nerd.
