You want to prioritize your financial structure. It is apart of the foundation of your business and will cause a lot of harm if you aren't hands on about it. Yes- Get one-on-one help from a financial adviser or consultant. If you want to get a CFO, make sure they are are not just capable- but are committed to your company's success. Having a CFO long term will be likely be the best option.

Personally, I am currently assisting a friend of mine with her start up company and her lack of financial structure is a source of conflict. You cannot expect success without planning for it, it's a part of the bloodline for your business!
