As an advisor myself, you need to prospect, prospect, prospect. Even the veterans of the industry struggle with lack of prospects at times. You need to be fearless on the phone, and effectively get referrals.
The financial planning knowledge will come with time. In the meantime, use planners that have been in the industry for a long time for their help once you have someone who wants to work with you. People will respect that you have matched them up with somebody who can help them, rather than tried to guess at what they should do yourself.
If you have good financial knowledge, great, but don't let that lead you to thinking people are going to start knocking the door down to see you. It takes years and years to build a sustainable business. The money can be great (I mean, you are a professional giving advice), but remember, 89% of the people who enter this business fail. Many more struggle, and just a few do everything right - provide top notch advice and service, and get paid handsomely to do so.
