Before you can ask such a question, you need to establish what you wish to do.
A "research" lab, "service" lab or "contract analysis" lab? What would be the product or service? Which companies currently provide the same product/service and who do they serve? How would your company differ or offer an incentive to buyers?
You should think about identifying what the lab will do (or provide) first, then develop a business plan which researches and evaluates the costs involved to establish and run it, how you will reach your customers and of course what income could be derived from such a venture.
