Then I would start with picking up the phone and calling all retreats, yoga studios, wedding planners etc in your local area.

I am not sure where to begin. with your septic and well you'll need to do site layout first with a land planner or the county. after that you'll need to check setback requirements and design plans and start budgeting with a builder. once you have a confirmed plan set and budget broken down and builder selected then you can talk to banks. most people think it starts with banks 

My biggest advice is to not use a financial planner, everything you need is on the Internet for free.

I am doing my due diligence to add an additional unit to a property here in California and the city planner said if it zoned R1 you can have up to 4 units.She also said that it cannot exceed 1200 sqft.

For Project Management, if you have Office365 Business it comes with Microsoft Planner which you can use for your FLIP and BRRR Projects.   

I talked to a planner in the city of Arvada.

@Jessie Dillon sometimes your financing will have requirement for this but I would absolutely recommend following every financial planner/advisors advice here - have 3-6 months of reserves saved up at all times.  

There was the leasing agent, planners, an interior design team to choose from the color palettes, others for security, construction inspectors, etc.

Beginner in REI and made bad mistake with " self directing " an IRA : now owe IRS big $$$so I need some assistance going forward 

With what you're trying to do I definitely recommend speaking to an agent that is familiar with what you're trying to do as well as a financial planner THAT ACTUALLY DOES FINANCIAL PLANNING.You'll come to find that most financial planners are 100% commission based life insurance agents disguising themselves as a financial planner lol.Good luck!
