Ask HN: Restructuring Maryland LLC

Hi HN,

A few years back, my partner on a small web venture started an LLC when he released a product. I was not as active at the time, so was not included in the LLC as a manager or shareholder.

Fast-forward 2 years later, and I am a major player in the company, handling all technology and marketing. We want to add me on with a significant amount of equity (40-60%) in the LLC but don't even know where to start looking or ask for help.

What can we do? Who can we hire? Or can we do it ourselves? What is the protocol here?

Thanks!
