Your question leaves a lot of detail out. Obtaining accurate 'business intel' can be as simple as subscribing to your local 'business newspaper', usually a weekly publication. Or spending some time in the local library.
Hiring a market research firm will give more information, depending on what you actually need to know, but you will pay for it.
