I've written extensively about this for Forbes, for my own website GoodCrowd.info, and elsewhere.
Equity Crowdfunding in general refers to multiple specific and distinct funding activities, most defined by the 2012 JOBS Act, which has not yet been fully implemented by the SEC.
Here are the features for quick background:
Title II: Now fully implemented, Title II allows general solicitation, that is public advertising, of securities offerings to accredit investors when following key rules. It requires help of an attorney, but is probably the cheapest fundraising strategy.
Title III: Crowdfunding, not yet implemented, will allow startups and other businesses to raise up to $1 million per year from ordinary as well as wealthy or accredit investors. The SEC is expected to issue final rules this fall.
Title IV: Regulation A+, fully implemented just 60 days ago in June, allows for an offering to ordinary investors but requires a formal offering document to be reviewed by the SEC. Think of this as a mini-IPO and shouldn't be thought of as a good alternative for first dollars in as the cost is significant.
In addition, many states now allow intrastate crowdfunding. This works best for real estate based businesses like restaurants as a business that will do business on the web is typically understood to be ineligible for raising money in a state. A single store restaurant could, however, raise money from investors in the state where it operates. The rules vary by state, but are generally very flexible and require very little to raise up to $1 million.
So, given that you have no cash and would need a lawyer, I don't think you're ready for an equity crowdfunding raise.
You may be able to raise enough money to pay for the legal work and such by doing a Kickstarter campaign. That would also be a great test market.
