Ask HN: What to do if you feel small company bound

Today is my 23rd birthday I figured I'd reach out to 23 entrepreneurs and why not ask hackernews a question as well :-)

The question: My startup budget can't afford any service right now though we make a 1.5k a month. I was wondering what your tips were for cold calling (not going super), when should one outsource sales(maybe we suck at it)? How would you contact 56 year old managing brokers of real estate companies? Out of our first 530 cold calls we've only converted 1 person in another state. I've made my first dollar, but feel small company bound.
