Information and advice please:

I am a 50 year old female, just sold a business, thinking about new ways to stay out of trouble. I've always managed my own investments, enjoyed it and done quite well. 

I don't want to take a "traditional" job, having already done my time with the 80+ hour workweeks.  My personal financial situation is very comfortable because of my business sale and a disciplined, debt averse financial strategy over the years...and a little bit of good luck of course.

 I've thought about becoming an investment advisor but would only desire to serve a selective clientele (friends and family, no need to pound the pavement and drum up leads). These are people who are encouraging me to go in this direction, ready to give me their portfolios to manage.  I have looked at Jones, American Express, UBS, but all seem to be too rigid for me and certainly require a full time (or more) commitment.

I assume that the Series 7 and Series 63 (for each state in which a client resides) is needed for what I'd like to do - and so is a Series 7 sponsor. Are there organizations such as networks of independent brokers (to which I'd belong once licensed) who sponsor individuals in situations such as I describe? I'd fully expect to pay all of the fees associated with my licensure.

I've read several other postings on this topic, but none seem quite relevant to this situation. I'm not especially worried about the exams, I'm a good student and a disciplined, focused person who has successfully completed a number of complex certification and licensure tests over the years.

By the way, I reside in South Florida in case that matters. Thanks for any and all insight or wisdom.
