You can look into the licensing requirements for your state. You may run into trouble as most states require a pre-determined amount of industry experience as a requirement.
My personal advice would be to stick around in your current role for a while longer. While I am sure you have learned a ton in one year you probably have not been around long enough to know what you don't know...
If you were truly serious about this proposition and you are VERY confident about the book of business and referral partners that you have developed, you would probably want to go work at a mortgage company for a while. The wholesale world is much different than the retail world...the business is far more focused on direct marketing and building trust over a long period. These are some of the features that are "built in" when you work for the bank. If you find that you have continued success over a period of two - four years working as a wholesale broker, then you could get serious about starting your own shop.
I would also add that a large barrier that exists now to the small shop model for someone such as yourself is that getting licensed FHA is much tougher now. Obviously FHA makes up a huge portion of the business in today's market and the new licensing requirements call for audited financials and (i believe) 1,000,000 in net worth. These changes take effect very soon per my understanding.
Without the ability to offer a full range of products it is difficult for a small shop to survive....and this change to FHA will be the death of many small brokers.
One last suggestion...there are a ton of shops out there that will essentially let you rent their license in return for a small percentage of your fees on each loan plus a small "per loan" charge. This allows you to orginate loans on your own and essentially be your own boss, without the complications associated with getting licensed on your own as a broker.
This is an increasingly common model for many successful wholesale originators.
Good Luck,
