Just a quick suggestion - if you end up seeking professional investment (VC, angel or SBIC) they will, most likely, require you to change your organization to a c-corp - either at time of their investment or upon an exit. While I think LLCs are one of the best forms of organizations out there - c-corps are simply better for investors. Do know that c-corps have many more requirements then other forms and are more expensive to manage - but, most professional investors will require it.
