Starting Fractional CFO - Consulting

Not sure if this is the best forum but posting here to start with.

Question: I'm trying to figure out how to best put myself out there as a fractional CFO slash consultant/mechanic. See background below. While I'm currently doing CFO work full-time, I think there's bandwidth for me to do some hourly/contract work on the side. Any suggestions on how to market and who to market to? I am very much a nose-to-the-grindstone type of person; the flashy suits and golf tournament type sales person ain't me. 

Background: I built my career in financial services, first in commercial/corporate banking and then in true small business lending through the alphabet soup type of entities (CDC, CDFI, CDE, etc). In between some of those jobs in finance, I went to work for one of my clients as a CFO to help them navigate early and rapid growth (ex: $3MM to $20MM in revenues over 2 year period) and was successful at this. Left that CFO gig to get back into finance, but had a reputation as somebody that can do it and was approached several times over subsequent years about other CFO gigs. I'm now back at another early stage, high growth entity and working to build foundations for growth and success here. Seeing that the owner was paying a "consultant" for at least 6 months before I arrived to basically do not much of anything and I'm wondering why I can't get some of that action on my own except I would actually do something to help clients. Not just take advantage of them and use fancy MBA-speak.
