Hazelford Funding, a small-business funding service in Lebanon, Tennessee, publishes practical checklists for Wilson County, TN owners: the city and county business license steps, a zoning and building permit checklist, a guide to Tennessee contractor licenses in a funding file, and a construction business loan calculator. They point to official sources and flag what to confirm with each office.
Calculator
The construction business loan calculator takes an amount, a rate and a term and returns the monthly payment, the total interest and the total repaid. It is built for comparing offers on contractor loans, but the arithmetic works for any fixed-payment business loan.

Shorter, practical articles on bidding, cash flow, shop equipment and office space are on the Hazelford blog. For the funding shapes themselves, start with the comparison page.
These guides are general information, not legal or tax advice. Confirm requirements with the office named in each guide, and ask a lawyer or accountant about anything that affects your obligations.
