Like another poster alluded to, save up some money (keep your job). Interview 5+ developers with entrepreneurial tendencies, pick one, thank the others, hire the one you picked, tier their compensation on milestones.
You already founded this, so looking for a co-founder is fairly moot. Hire someone, give them a chance to shine, bring them in as a partner. If trying to force the "tech co-founder" isn't working, try something else. As for outsourcing...I think it is a silly word that means "not committed". You're not committed to them, they are not committed to you...in the end you have your prototype, but know far less about it then if you hired someone, even an intern, and had them walk you through their process and the code...most outsourced help would probably not do that for you. A less risky move is to hire someone on 1099 for the project...you probably know more about those rules than most.
If you waste too much time fretting over the details, you'll never get it off the ground. Check your balls, take the leap. You will never be 100% correct (you damned accountant! : ) so take your best shot and learn what you are made of.
Post an email link or phone number in your about and I'll give you a call and a swift kick in the ass if you need it.
