I have been bootstrapping for 4 years, it's getting harder. I know what to build and I'm a solo founder for a software network-security-related product. I'm advised to hire contractors from elance.com and such and pay them to speed up the development, in the meantime someone mentioned the code will be difficult to maintain, or you can not really control the schedule, or the time you spent on managing the contractors will distract you from what you are doing badly... Someone else suggested the VC route, which I have not tried, I'm essentially the only developer with 20+ years of network security experience and know what I am doing. However getting involved in VC is another huge distraction to say the least for me, plus all the negatives coming with it as others stated on the internet. I don't really need VC's money for the status quo, I can afford a few overseas contractors(cheaper), I can self-sustain just fine for yet another two years. But it's slow and making me a bit exhausted. If I hire local engineers or contractors in US, I do need financial help from VC or somewhere else. And, I tried to find partners, so far no success, in the end I'm fine with sole founder for the moment. YC etc does not help as I can not go there for 6 months for family reasons. I live in Austin,TX.
