What funding programs actually helped your business grow and which ones should you avoid?

I own a residential/commercial cleaning and interior painting company in Indiana and I’m trying to grow responsibly. Between equipment, payroll, insurance, marketing, and vehicle costs, expenses add up quickly.

I’m looking for legitimate grants, low-interest funding, or small business assistance programs that actually helped your company grow — especially for service businesses.

Any real experiences, recommendations, or programs to avoid would be appreciated.
