The business plan will help you understand the market and what you need to be successful. It in effect allows you to make some of your mistakes on paper. Alot cheaper!
Understand what the value of your services are. How does it enhance property value. Reduce maintenance costs, utility costs. What are the laws that affect what a homeowner needs to do with their trees and their liabilities. Considering that you work at a golf course many potential clients see your work everyday!
I'm sure you can find self-employment training programs thru HRDC in Nova Scotia. Whatever big equipment you'll need initially can be rented until you have the cash flow to buy. Figure out what is the bare minimum you'll need, i.e., chainsaw, climbing gear, rigging rope, truck with a dump box. As for dumping location, we don't have a big yard but have found sites in and around the city. Chips used for mulching tree plantings, covering trails, etc.... Since there is a demand for firewood then you've got a market for your wood. Whether you sell the good stuff and give away the junk, it'll go.
Good luck!
