There's a bounty waiting as your company grows beyond that one man startup but also a lot more stress. But it's that very Stress which will enable you to grow. So embrace it, buckle up and work your ass off.
1) I also suggest partnering with pros that need YOU and develop a service bartering agreement.
2) Network like hell for contractors before a job surfaces, it's usually too late to spec jobs and kick off projects safely.
3) Do only what you're GREAT at and this will afford you more time to work on projects.
