Has anyone hired a fractional CFO?

[Matthew Bailey]

I own a land investing business, similar to wholesaling but with vacant land, and we take title to the properties (we don't do assignments like wholesaling).  It's highly transactional, this month we'll do probably 10-15 deals.  The financial modeling and forecasting is an area where I could use some help.  I know the financials are sound, however I'd love to have someone model the business and be able to answer questions like "What if conversions decreased by 25%, or the market fell 20%, how does the business model look then?"  I don't know for sure how much runway to keep liquid (I'm presently keeping 5 months of runway liquid, I.e. salary, overhead, all expenses) since we don't have passive income, it's all active income from cash deals.  Is that too much, too little?

Basically the cashflow in and out of the business is getting more and more complex, I want to be sure that I can take care of the four full time employees that I have, I simply feel like I need a professional finance person to look at what I'm doing so we can come to conclusions about if that's appropriate, and how we can improve it.

So has anyone hired a "fractional CFO", i.e. part time/on demand CFO.  I think that could give me a lot of peace of mind, as some unforeseen market shift or increase in competition impacting the financials is what keeps me up at night.  I think that a professional opinion on how the business is being run, its vulnerabilities, how to protect against the downside, etc, could all be of benefit at this stage of scaling the business.
